Summer water supply in the country from polypropylene pipes - device options. Irrigation system in the country from plastic pipes Pipes for water supply in the country which are better

The importance of a full-fledged water supply in the country can hardly be overestimated. Without a constant water supply, maintaining the site becomes an extremely time-consuming task, and ordinary dishwashing turns into a real test, not to mention the use of modern household appliances that require a connection to the water supply and.

That is why almost every owner suburban area wants to equip a full-fledged plumbing. It is quite possible to cope with the solution of this problem with your own hands. This is, firstly, invaluable experience, and secondly, a great opportunity to save money by refusing the services of third-party masters.

Features of the device of a private water supply

It is better if the planning of the water supply will be carried out even at the stage of drafting the project of the summer cottage and the house. A full-fledged project includes a number of drawings and documents, including:

For you need to allocate a small room on the ground floor of the house. A room of 3-4 m 2 will be enough. It is more convenient when the water inlet node and the necessary technical devices located in the same room - this gives the owner the opportunity to fully control the process of water supply.

A typical private water supply system includes the following equipment:

Choice of source of water supply

In the process of designing a country water supply, you need to choose the optimal source of water. Check out available options and choose the most suitable for your case.

The most simple and convenient option. It is important that the pressure in the system is sufficient to deliver water to the building. Otherwise, you will need to additionally buy a pump or consider other methods of water supply.

Water will be supplied to the building through a system of pipes and fittings.

In this case, for the installation of a water pipe, you usually do not need to buy any additional devices - you just need to dig a trench, lay the elements of the water pipe and crash into the central highway.

If there is no access to the central highway, consider the following options.

The method is suitable for areas with a depth of an underground aquifer of at least 8-10 m.

A shaft for a well is equipped with the efforts of 2-3 people - alone it is too long and difficult.

The main advantage of this option lies in the extreme simplicity of the system - it will be possible to care for and repair it on your own. The maintenance of such a well in a normal state does not require tangible costs.

The main disadvantage is the severely limited water supply. Not every individual well will be able to provide as much water as is necessary to meet all the needs of the family.

Before giving preference to this option, calculate the amount of water you need and establish how much water the well can produce.

Arrangement plumbing system based on a shaft well requires the use of a surface pump. The equipment is relatively inexpensive and easy to maintain.

Well

If the underground aquifer lies deeper than 8-10 m, a well will have to be drilled. Pleasure is not cheap - drillers charge quite substantial money for their work.

But, having spent money once on arranging a well, you will secure your dacha clean water in required volumes. If you want to save money, you can try to negotiate with your neighbors and make one well for several houses.

To equip the water supply system in this case, you will need a special borehole or. Such equipment is much more expensive than its surface counterparts, but in terms of the efficiency of providing clean water, it has no equal.

Summer and winter plumbing

Previously, you most likely heard such definitions as summer and winter plumbing systems. Study the main properties of these options, it is quite possible that even the simplest summer option will be able to satisfy your needs. Otherwise, you can immediately proceed to the study of the following sections of the manual on the arrangement of a full-fledged water supply.

Summer option

The features of such a water supply system are clear from its name - the operation of such a system is possible only in the warm period. There are stationary and collapsible modifications of the system.

Collapsible summer plumbing has a very simple design: it is enough to connect the hoses to a pump of suitable parameters and lay them on the soil surface so that they do not interfere with normal movement around the summer cottage.

Silicone and rubber hoses are suitable for arranging the system. The connection is made using special adapters. Also in specialized stores are available more modern products for connecting hoses - latches. One side of such a latch is equipped with a spring-loaded connector, and on the other side there is a “ruff”. With the help of such latches, hoses are connected quickly, reliably and simply.

Most often, such a collapsible system is used for irrigation. It is pointless to organize on its basis a full-fledged water supply to solve domestic needs.

The laying of a stationary summer water supply is carried out underground. Flexible hoses are not suitable for arranging such a system. The best option- plastic pipes.

Pipes of stationary seasonal water supply are laid at a meter depth. After the end of the season, water must be pumped out of the pipes, otherwise, with the advent of cold weather, it will freeze and ruin the pipeline.

In view of this, the pipes must be laid with a slope towards the drain valve. Directly the valve is mounted near the water source.

Winter option

Such water supply can be used throughout the year.

Pipes made of polyethylene and polypropylene are suitable for arranging the system. The former are sold at a lower price and are mounted without the use of special tools. The latter are somewhat more expensive and require the use of a pipe soldering iron during installation. However, in the end, you will spend more money than for additional products used in the installation of polypropylene pipes.

Water pipes are laid with a slight slope towards the source of water supply. The pipeline should run 200-250 mm below the freezing point of the soil.

There is also an option with pipe laying at a depth of 300 mm. In this case, additional insulation of the pipeline is mandatory. Foamed polyethylene perfectly copes with the functions of thermal insulation. There are special products of a cylindrical shape. It is enough to simply put such rounded polypropylene on the pipe and as a result the product will be reliably protected from cold and other adverse effects.

Not only winter water pipes, but also a source of water need additional insulation.

For example, a well is insulated for the winter and covered with snow. These measures will be enough to ensure the protection of the structure from the cold.

superficial pump equipment if used, it is equipped with a caisson. The caisson is a pit with additional insulation, equipped next to a water supply source equipped with a pump.

The installation of automatic pumping stations can only be carried out in a room where the air temperature does not drop to negative levels even in the most severe frosts.

The sewer system also needs to be insulated. In the absence of it, the drains will freeze and disrupt the operation of the drainage system.

Water pipes

Drafting a project

Start by designing the system. First of all, decide on the equipment. Specify the location of the water intake points, calculate the required number of fittings, select the optimal material of manufacture and type of water pipes.

Plastic pipes are used most often. These are durable and reliable products that fully cope with all the tasks assigned to them. At the same time, plastic pipes do not rust, which allows them to be sewn into walls, unlike metal counterparts.

Make up detailed diagram future plumbing. Indicate all dimensions on the drawing. So you can calculate the optimal footage and determine the required number of components. At the same time, it is recommended to buy components with a 10-15 percent margin.

Also, you must decide whether you will choose and buy everything yourself. necessary equipment, or immediately buy a ready-made water intake station. At this point, be guided by your personal preferences.

Installation of plumbing system components

First step

Dig a trench from the water source to the point where the pipe enters the building.

Second step

Deep-type equipment is lowered into the water supply source. Surface pumps are mounted next to the well or well. The pump is installed in a heated room or in a caisson.

Third step

Connect the water pipe to the installed pump. Attach the free end of the connected pipe to the five-pin fitting.

Fourth step

Connect the storage tank, pressure gauge, and pressure switch to the free outlets of the fitting. The volume of the storage tank can reach 400-500 liters and even more. Thanks to this device, optimal will be provided. In addition, you can store water in the storage tank in case of unforeseen situations.

Fifth step

Connect the pipe to the remaining free fitting outlet, and then run the line along the previously leveled bottom of the dug trench straight into the house. Also, along the bottom of the pit, you need to lay a protected cable to connect the pump and accumulator.

It is important that the socket intended for switching on the units mentioned above is properly grounded.

sixth step

Install a shut-off valve in front of the pipe entry point into the building. It will allow you to shut off the water supply if necessary.

seventh step

After making sure that the external pipeline is working correctly, fill in the hole and proceed with the installation of the internal wiring.

Regardless of the selected source of water supply, it is strongly recommended that the water supply system be equipped with cleaning devices.

Perform internal wiring in accordance with the previously prepared diagram. At this point, focus on your preferences. Do everything so that in the future it is convenient for you to use the connected water supply.

In conclusion, you will have to equip the water intake points by connecting faucets, appliances, etc.

Providing hot water

If you need to provide hot water, you can complete your plumbing system with a water heater. There are accumulative and flowing varieties of such equipment. In summer cottages, it is most convenient to use storage tanks.

The installation of the water heater is carried out according to the standard scheme for such equipment.

Now you know in what order the installation of the plumbing system is carried out and what needs to be taken into account for the successful implementation of all related activities. Do everything in accordance with the provisions of the above manual, and your plumbing will work properly. long years.

Successful work!

Video - Do-it-yourself plumbing in a country house

Country water supply from plastic pipes not much different from the analogue in ordinary apartments. The thing is that here it is necessary not only to bring water to the valves and household appliances but also to provide irrigation system.

The latter reason puts high demands on the performance of the pump and the stock in the well.

The reality looks in such a way that the power supply is often turned off in summer cottages. For this reason, it is necessary to consider a reserve supply of water.

Some nuances of laying the plumbing system in the country

The device of a summer water supply system made of plastic is produced as follows. The water supply in this case is carried out through pump, which supplies fluid from a storage tank or accumulator.

When installing a storage tank, the liquid supply will be equal to the volume of the reservoir tank. But, its bottom should not be located below the water intake points. Then there will always be water in the taps.

Using a hydraulic accumulator is more convenient because there will always be constant pressure in such a system. If a pump and an automatic pressure switch are added to this device, then the whole structure will be called a pumping station.

Such a system is embodied in the summer and winter options. The difference between the systems will be in the place of installation of the equipment.

Which pipes are better to choose

Not so long ago this was not an issue. Water pipes for summer cottages were used only from steel.

On the this moment metal options are practically not taken, because an excellent alternative has appeared - plastic counterparts.

For suburban area better option is not found. Such pipes do not rust and do not deteriorate from the influence of low temperatures.

Only when buying, you need to take into account the fact that plastic water pipes are different:

• HDPE. Low-pressure polyethylene. Such products are attracted by the fact that they are designed without auxiliary elements. Fittings for working with such materials are threaded and easily twisted by hand.
• PVC. These pipes are for country house are used very often. They cost less than the previous version and are fastened by cold soldering (glue). The seam on such blanks comes out strong and reliable.
• PPR. This kind of plastic pipes can be applied to cold and hot water and for the heating system. Connect these materials by soldering and couplings.

When installing a water supply system from plastic pipes, you need to know that its price compares favorably with a pipeline made of metal materials.

The price for blanks for PP pipelines is as follows. This is from 1 to 7 dollars per linear meter. Approximately in such limits is the price of fittings.

The most expensive materials of this type are supplied by German and Italian firms. Products from Turkish and domestic manufacturers are an order of magnitude lower.

In order for the pipeline to serve smoothly, it is advised to purchase only high-quality goods from trusted manufacturers.

Such a product is a little more expensive, but this is fully justified by the long and reliable operation of the built system.

Do-it-yourself plumbing system construction

See at the end of the article a detailed video instruction on how to supply water to a private house

It is not difficult to construct a summer water supply system from plastic with your own hands, if you carefully study all the subtleties of this matter.

• First you need to choose a source of water. The cheapest way is to build a well. Also, a sand well may well be suitable for such purposes. Although the best method is an artesian well. Its service life adds up to almost 50 years.
• Summer plumbing. Already from the name it is clear that this building is used only in summer time. This network can be collapsible, and permanent. Most often, in this case, the hoses are simply pulled along the ground. And for permanent summer version blanks are hidden in the ground so that they do not interfere on the surface. One drawback of such a structure is the exposure of the slope to the connection point of the main network. At the location of the lowest point of the water supply, a drain valve is installed to drain the liquid for the winter period.
• Winter view of the pipeline. This design refers to the capital system, which can be used at any time of the year. To supply fluid, install submersible pumps. The power of such a mechanism is selected in accordance with the depth of water supply. Also, for such equipment, you will have to connect a power source. Cable and water supply are allowed to be displaced in one casing made of plastic blanks for a drain pipe network. He will excellent protection from freezing and mechanical influence.

Irrigation organization

Water supply for irrigation in the country is a construction of essentials. The "dacha" stage of life begins with the arrangement of the water supply.

As already mentioned, there are temporary and permanent systems. But, the construction of any of them begins the same way - this is the development of the project.

When designing, the following nuances must be taken into account:

• Plastic pipe-rolling joint is carried out at a slope relative to the water intake.
• They are brought to the surface only in consumption areas.
• The use of polypropylene materials will make it easy to mount and remake the structure.
• The depth of the trench for the summer water supply should be forty centimeters. Under passing beds, this distance is recommended to be increased, otherwise the pipe network can be damaged during planting.
• For a collapsible view, rubber hoses are often used, which are connected with jumpers or special clips. Such fastening makes it possible to separate or fasten two pieces of water supply in one movement.
• The location of the beds determines the number of points of consumption. To facilitate the irrigation process, it is advised to bring the pipe out in at least five places.

Do-it-yourself water supply design

Do-it-yourself water supply for irrigation is not difficult to create. After the development of the project, earthworks begin.

The submersible pump is lowered into the well or placed in a nearby recess, which is insulated. It can be placed directly in the house itself.

If necessary, a pressure testing device and a pump are installed. After that, the pipeline is pulled along the trench to other points of water analysis.

The battery for powering the pumping mechanism is recommended to be carried out in a protected cable. In any case, electrical safety must be taken care of.

In this case, it is impossible to do without installing sealed connectors and grounded, moisture-proof sockets.

To enter the pipe into the room, an emergency shut-off device is installed. After checking the operation of the country pipe line, the recesses can be covered with earth. Now you can proceed to the installation inside the housing.

Device inside

To make the use of the pipeline comfortable, you need to worry about hot water supply.

This is achieved by installing electric or gas heating units of storage or flow type. In the country it is more profitable to put storage water heater.

Let's take a closer look at their pros and cons.

The polypropylene pipe network will not “announce” the repair soon. This is facilitated by the excellent technical characteristics of these products.

Such blanks are easy to mount, they are not afraid of temperature changes, and the joints do not reduce tightness at low temperatures.

IMPORTANT! When building a water supply system in a country house, it is imperative to check the sample from the water source for purity. Based on the results of a laboratory study, a multi-level filtering network is installed.

Dachny plastic plumbing will bring convenience and comfort to the standard of living outside the city.

Modern materials allow you to build a system that will allow you to enjoy all the benefits of modern civilization, with your own hands in a short time.

And the cost of polypropylene materials will not create large financial costs at the same time.

Entries

Plumbing in the country, even if it is a summer, temporary option, performs many important functions. This is watering the garden and the garden, street needs, Summer shower, bath water supply, even at home, if the design is made in the capital version. In order for the system to please and work smoothly, it is necessary to pay attention to all its components. Especially important right choice pipes - different materials serve different purposes. For example, the functions and creation of a water supply system in a country house made of HDPE is fundamentally different from the temporary version of rubber hoses.

Before you take care of country water supply, you need to decide on the option of water supply. In a city apartment, everything is very clear: water is needed in the bathroom, bathroom, and kitchen. As for the option for giving, before choosing materials for work, you need to decide why you need it?

The simplest option is a summer collapsible design for irrigation, garden needs, and a shower outside. Its peculiarity is that the pipes are laid on the surface of the soil, and for the winter they are disassembled and cleaned in a warm place. Therefore, the materials for its creation can be almost any. The option of a stationary summer water supply also does not involve the use of particularly resistant materials. Pipes in this case are located in trenches underground, but for the winter the water is drained from them, which means that they cannot freeze and crack.

Ownership country house gives unlimited opportunities for the manifestation of creativity, imagination. Many choose...

It is a completely different matter - capital, permanent water supply. It is manufactured in accordance with all the rules, with laying pipes underground in frost-resistant insulation. Such a system is suitable for year-round operation. Therefore, especially strong pipes are used here, which are not afraid of frost, temperature changes, boiling water from the inside. In addition, they must be durable, because every two or three years, digging up the ground and changing the water supply is not the greatest pleasure, and it is also very expensive.

For the construction, it is very important to choose the right pipes and insulating materials for them, because the service life will depend on this. Each material has its pros and cons to consider.

Having decided on which system and for what purposes you need, you can choose pipes for plumbing in the country.

What pipes are

At the end of the last century, there was no doubt about the choice of water pipes. All because there was no choice: metal pipes were the only option on the market of the past. Now, mostly plastic pipes are used. But plastic is a very conditional concept. There are many options for polymeric materials, and each of them has its own advantages and disadvantages.

However, metal pipes should not be written off, they are still used, albeit not as common as various plastic options. Generally speaking, you can create a water supply system in the country with your own hands from the following materials:

• rubber hoses;
• black steel;
• Cink Steel;
• metal-plastic;
• polypropylene;
• HDPE (low pressure polyethylene);
• PVC (polyvinyl chloride).

The choice of material depends on how the water supply is supposed to be used. Therefore, it is impossible to say which material is better and which is worse.

For the summer collapsible version, light, easy-to-install, well-understood tubes are suitable. For capital, those are required that are resistant to corrosion, withstand temperature extremes, pressure and other influences well.

Types of pipes

All materials have their own advantages and disadvantages. Next, let's take a closer look at what different pipes different than they better, and the worse their "competitors".

Rubber

Rubber hoses are a variant of a country water supply, if it is a summer collapsible design. Rubber is a flexible material, so such tubes can easily be on the ground without interfering with any work and moving around the site. Irrigation plumbing, that is, one that is used exclusively for irrigation personal plot, just well made of rubber, due to its flexibility, maneuverability and ease of installation.

black steel

Black steel is a high strength material. However, at present it is not very popular due to the fact that it is difficult to install and prone to corrosion. The first problems with such pipes may appear in five years. But pipes made of black steel are not afraid of almost any mechanical impact. They are durable, impact resistant high pressure, as well as its differences and temperature differences.

Cink Steel

Unlike its predecessor, black steel, galvanized steel is resistant to corrosion, while also maintaining high mechanical strength. It would be an excellent material if it were not for the complicated installation. So, to work with metal, welding is required, as well as the creation of threads.

metal-plastic

This option combines the advantages of metal and polymer materials. When creating such a structure, an aluminum pipe is placed between two polymer layers. Thus, it turns out that the metal is reliably protected from the inside and outside, which means that it is not subject to corrosion. And due to the metal base, the pipe is durable, resistant to any impact.

At the same time, metal-plastic pipes on the market are represented by a variety of options for affordable price and installation is quite simple.

Polypropylene

Polypropylene is essentially a type of plastic. The design of the summer water supply in the country from polypropylene pipes is quite durable, while being easily mounted and dismantled. In addition, this material is also suitable for a capital year-round system, since it is presented in various options:

• for sewerage;
• for cold water supply;
• for hot water supply;
• for heating.

Polypropylene plumbing is resistant to hot and cold temperatures. Therefore, this material is used not only in private households, but also for industrial needs. Such pipes are connected by soldering.

HDPE (low pressure polyethylene)

It is currently one of the most popular materials. We can say that HDPE pipes for water supply to the country house are ideal. Judge for yourself. So, this material allows you to assemble the system without the use of additional equipment, since all fittings are already threaded, and you can tighten them by hand without much effort.

The system of HDPE pipes is very durable, can last up to 50 years. This is because this material does not rust, does not corrode, is resistant to chemical and mechanical stress. In addition, it withstands high temperatures, and when water freezes, it does not burst, but stretches. Therefore, even if you forget to drain the liquid from the HDPE pipes of the summer water supply for the winter, nothing very terrible will happen.

Various variants of such pipes are suitable for low and high pressure.

PVC (polyvinyl chloride)

PVC is another popular modern option for making pipes. Their cost is lower than that of polyethylene. However, some qualities are also lower. Mounting of the structure is carried out using cold welding. With proper use, the useful life is also 50 years.

However, such a pipeline is afraid of mechanical impact. In the presence of scratches, the strength of the entire structure suffers, so the option is completely unsuitable for summer surface plumbing. If you choose PVC for a stationary structure, then you need to consider two points. First, they can only be laid in isolation. Secondly, they cannot withstand temperatures above +45 and below -15 degrees Celsius. This means that PVC plumbing is only suitable for summer stationary cold plumbing.

Fittings for plastic pipes

When creating a country water supply system from plastic pipes, it is important to choose the right not only a variation of this material, but also to select the necessary fittings for it. The most commonly used are:

• couplings for the tightness of the joints of pipes of the same diameter;
• adapters for connecting pipes of different diameters and connecting to the main line;
• tee coupling for easy liquid drainage;
• threaded coupling for combining a pipe with a long-standing plumbing system using threaded connections;
• flange connection for connection to the water discharge manifold;
• coupling-"saddle" for connecting a pipe of smaller diameter to the main line;
• coupling-plug to create tightness of the end of the pipeline or to disconnect.

In addition, given the fact that HDPE pipes, for example, do not bend at a right angle, there are special connecting swivel fittings.

It is important that the strength of a water supply system made of polyethylene pipes largely depends on the correctly selected fittings and the correct installation.

There are other options for fittings. In any store, when choosing pipes, they will help you choose additional suitable elements.

Mounting Features

Having decided on the features of the water supply system, you can proceed to the preparation and installation of the selected structures.

1. We make a plan. The scheme for arranging a country water supply should take into account all the features of the site. It is also necessary to make all the necessary measurements.
2. We choose materials. You should choose and purchase materials only after deciding which pipes you will use and how many you need.
3. We free the site. During installation, nothing should interfere with the process.
4. Let's start earthworks. This item is relevant if a capital water supply is being built. If the system is shallow, trenches do not need to be dug.
5. We install pipes. Pipes are laid in place, fastened together.
6. We connect all systems. Then you can connect the system to the pumping station and check its operation.

If after installation everything works according to the best scheme, you can dig trenches, not forgetting about insulation, of course.

After pleasant, but tedious country chores, I really want to wash off all the fatigue of this day under warm jets of water ....

Conclusion

Currently, choosing pipes to create a water supply system in the country is not a problem. The variety of materials, shapes, sizes is huge. There are pipes literally for all occasions and for different situations: for creating heating, for cold and hot, for sewage. The diameter of the pipes, their resistance to temperature and pressure are also different.

Preference is given now different options pipes made of plastic, polyethylene. They are durable, resistant to corrosion and wear. Structures made of polymer variants do not rust and, with proper, careful operation, can last for many years.

The organization of water supply and sewerage in the country is a very important issue. It is from the solution of this problem that the comfort of living in summer house and the presence of an irrigation system. During the initial design, you need to determine whether you will use it in the winter or everything will be limited only to the summer. The depth of pipe laying depends on this, because at sub-zero temperatures they can burst from the presence of ice inside.

Best would be to use polyethylene pipes, and the wiring diagram should be prepared in advance. It will depend on the source of water supply and the method of transporting it to the place of consumption. Installation of such a system can be done by yourself or entrusted to professionals.

How to make plumbing in the country from a well: a scheme for laying plastic pipes

Before you conduct plumbing in the country, you should decide where the water will come from. If you chose a well as a source of water supply, because of its low cost compared to a well, then the pipeline is best made underground. But first, you need to find a place where there will be enough water. To do this, using a hand drill, a recess of up to two meters is made, inside which a drainage pump is placed. Depending on the volume of incoming water, you can determine its power. If enough liquid is collected, then the hole is dug in diameter and placed inside concrete rings.

The layout of the water supply in the country begins with a pipe coming out of the well, it is located at its very bottom, parallel to the ground level. After its withdrawal and sealing of the joints, you can proceed to digging trenches. A marking is made on the ground, which corresponds to a scheme thought out in advance, and the excavation begins on it.

Pipes for water supply in the country are used plastic or PVC. In the modern version, they are quite resistant to pressure drops and even withstand several freezing seasons. To create pressure in such a system, a pump must be laid, but it is placed in a separate room. The less environmental impact, the better.

The water supply scheme may include not only country house, but also watering the site. Pipes for its organization are buried shallowly, but before the onset of frost they must be freed from water.

Winter and summer water supply in the country: differences in the device and pipe insulation

Do-it-yourself country water supply is easiest to make from hoses that will lie on the surface of the earth. In this case, it will be called summer, because at the end of autumn they are rolled up and put in the pantry until it warms up in the spring. The most convenient for connection are plastic fittings, which have special "Christmas trees" on them, the hoses are simply put on in one motion. The pipes themselves are made of durable rubber and proper care will serve you for more than one year. The main thing is to wind them in neat bays without inflection areas during storage.

Country water supply from plastic pipes is more resistant to weather conditions and can even be buried in the ground. The standard service life of such material is more than fifty years. Pipes are absolutely not subject to corrosion or other chemical influences. Do not forget that to avoid freezing, pipes should be at a level of 1-2 meters underground. In this case, the operation of the water supply will be available all year round.

If you want to avoid the hassle of digging deep trenches for winter plumbing in the country, then get an electric heating cable. True, when using it, electricity bills can increase significantly. Another simple way out of this situation can be the insulation of the water supply in the country. As an insulating material, merylon can be used, which has a different diameter and tightly covers the pipe with the right selection. If it is not there, then get glass wool, it is also used in hot water systems.

Do-it-yourself water distribution in a private house and in the country

Properly executed water distribution in a city apartment or a private house provides a high level of comfort.

The well-appointed apartment has a bathroom and cold water considered the norm.

It is impossible to do without water for irrigation in the country.

Water supply of a private house

In a private house built according to modern project, mechanisms for the delivery of cold and hot water are provided.

On the site adjacent to the house, as a rule, a certain landscape is formed and a place is allocated for a traditional vegetable garden.

These objects require abundant moisture for watering.

You can not do without water and in the bath, which must be on the estate without fail.

Water for all needs (for the bathroom, irrigation, in the bath, etc.) is taken from various sources.

Where does the water in the living quarters come from?

A person living in a city apartment does not think about how and where the water comes from in the bathroom. Similarly, in the bath, where with hot water there are no problems.

Things are different in the countryside. Here, the owner of the site, often - has to mount the piping for irrigation with his own hands.

Technically savvy summer residents use a manifold for distributing pipes and hoses, instead of the usual tees.

Each gardener, laying pipes around the site, knows from which source water comes for irrigation.

There are four main sources of water:

• open reservoir;
• centralized water supply network;
• wells;
• wells.

Wells, as sources of water, are mostly a thing of the past. They continue to be used mainly as a backup source and as a decorative element in landscape design.

In a modern private house, most often water is pumped from a well. As a rule, such a water supply scheme is used for estates that are located outside the city limits.

If the house or cottage is built in the immediate vicinity of engineering networks, it is technically easier to “crash” into an existing highway.

In this case, significant investments in drilling and well construction will not be required.

Centralized source

If there is no water in the apartment of a multi-storey building, then the residents call the control room of the water utility and find out when normal water supply will resume.

In the same way, people living in a private house have to act. It is impossible to correct the situation with your own hands in such a situation. The bathroom cannot be used. Wash dishes too.

When deciding to connect to a centralized water supply network, this must be remembered.

It should also be taken into account that in this case it will not be necessary to deal with drilling a well, acquiring expensive equipment and organizational issues. There will be less hassle.

decentralized source

Among the sources of this type are rivers, lakes, wells and wells. If there is no natural reservoir in the district, then it is necessary to carry out geological research on the site.

This is done in order to find the aquifer and determine its depth. It is more convenient and cheaper to make the well located in the basement of the house.

With such an arrangement of the source, it is much easier to mount the pipeline wiring around the site, as is done in the country. In summer, a lot of water is required for irrigation and in any season it is needed in the bathhouse.

The debit of the well must be higher than the volume of water that is consumed in a private house and other places.

Current water supply schemes

How to make plumbing in a private house?

If we approach the topic in principle, then the plumbing scheme in a private house has much in common with how water is distributed in ordinary apartment multi-storey building.

To do this, you can install a pump with your own hands, which creates a pressure of two to three atmospheres.

On the fifth floor and above, the water supply for the bathroom and other needs is carried out by more powerful pumps.

It follows from this comparison that plastic pipes can be used in a private house, which are more technologically advanced and much cheaper than metal pipes.

The connection scheme for water fittings is of two types:

• collector;
• consistent.

The sequential circuit is the simplest in terms of the principle of operation. It is often mounted in the house, and in the bath, and in the country. Installation work, in order to save money, you can do it yourself.

And in the bath, and also, if there is a need, in the apartment - the main pipe is laid. Tees crash into it, at pre-marked places.

From a specific tee, a pipe or hose is laid to the water heater or to the shower, or to the washbasin. This connection scheme allows you to get by with a minimum of pipes.

However, the pressure of water in the system will decrease with distance from the source. At the most remote connection, the pressure will be the weakest.

This situation is familiar to people who live in an apartment on the upper floors of high-rise buildings. The collector circuit is devoid of such shortcomings.

The collector is a device for uniform distribution of water between consumers.

Collector piping has a more complex configuration.

Its cost is higher than with serial laying. Higher because installation requires more running meters pipes. With all this, the collector provides a better water supply.

Collector system in the apartment

Modern apartments have a free layout and often occupy two levels. In this case, the water distribution scheme is developed individually.

You can install pipelines and install plumbing fixtures in the bathroom with your own hands. However, it is preferable to entrust these responsible works to professionals.

It is not recommended to install a collector, and maybe more than one, without proper experience. In this case, the risk of flooding neighbors from below increases.

To avoid such troubles, plastic pipes are connected with a special welding machine. In the country, for watering the beds, hoses connected by wire couplings are used.

When installing a pipeline in a city apartment, such connection methods are not suitable.

To make a strong connection, a special tool is used - scissors, napkins for cleaning grease, nozzles of the appropriate diameter.

Such a connection reliably serves in circuits for supplying both cold and hot water.

Material selection

When laying a pipeline from a well to a house or bath, it is preferable to choose from plastic. Polypropylene pipes are widely used in the country and increasingly in the apartment.

They are easy to install and their price, in comparison with pipes made of other materials, is low. The collector is made of copper or brass. Rarely stainless steel.

It is used to distribute both cold and hot water. In the apartment, for the bathroom, you can make a reliable wiring with your own hands from copper pipes.

In the country or in the bath, such a luxury is simply not needed. When planning the execution of certain works, you need to properly use the available opportunities.

Steel pipes continue to serve for water supply in the country, in an apartment and in a private house.

For laying a steel line, along the section from the well and to any point with your own hands, you will need to use a welding machine.

And, plus to it, considerable physical efforts. Practice shows that some owners of private properties prefer to use traditional materials.

Both in the bathroom and in the country, plastic structures are extremely rare. At the same time, a copper collector is considered a completely acceptable option.

Do-it-yourself installation is quite within the power of a person who is familiar with the installation rules.

The specifics of installation work

Before proceeding with the installation work in the house or in the country, it is necessary to purchase all the necessary devices, materials and components.

An exhaustive list is contained in project documentation. To install in the bathroom - you need the bath itself and a faucet.

The collector is installed in the room where the water distribution unit is located. All pipes and adapters must be properly assembled so that there is no confusion during installation.

When laying the pipeline along the section from the well to the bath, you need to carefully check the quality of the pipe connection.

When performing work inside the house - pipes, a collector, valves are attached to pre-designated places.

The pipeline laying scheme is designed so that there are as few transitions “through” the wall as possible. This also applies to the bathroom and other rooms.

When the collector is attached, there should be a distance of 20–25 mm between it and the wall.

One of the laws of hydrodynamics says - the fewer turns and angles in the line, the less pressure loss.

It is desirable to observe this rule both when laying the line from the well to the bath, and when installing pipes indoors.

It is also preferable to mount the collector on a straight section of the pipeline.

By following all the installation instructions, as well as following the advice of experienced professionals, all water distribution work in a private house will be performed with high quality.

Do-it-yourself plumbing in a private house, video, diagrams

In a private house, water can be supplied in two main ways:

• through private sources;
• through the central water supply.

The first method involves the supply of water from wells or wells, which are located on the site of a private house. This material contains videos, photographs, as well as diagrams that will help you make the water supply in a private house or in the country with your own hands. We will analyze how the wiring is performed, and what is needed for this.

Interesting: sometimes the source can be a lake or a river. But today it is practically impossible to meet such a water supply system, since all water bodies located near enterprises are polluted. The way out can be a special treatment complex.

Water supply from a private source

Installation of water supply in the country should begin with checking whether private water sources are suitable sanitary standards be it a well or a well. This also applies to large reservoirs from which it is planned to draw a resource. The well is considered the most reliable, as it functions in any conditions. Turned off the electricity? We raise water on buckets with our own hands! In other cases, the work is done by electric pumps.

Nothing will stop you from equipping this beauty electric pumps.

If long-term work on the well does not attract, then as an alternative, you can make a well with your own hands. Usually it is performed in the basement of the building. The main plus is that there is no need to lay pipes from the well to the main water supply system. You also get a strong pressure, because electric pumps pump liquid from close range. Such a source of water also has its drawback - the well is flooded, as a result, every 3-5 years a thorough cleaning is necessary.

Depending on the amount of water, the possibilities of wells differ. In standard cases, the owners create a well, the width of which is 10-15 centimeters. Such a system allows you to receive liquid using an electric pump, but you will not be able to raise several liters of water with your own hands.

It looks like a water supply system installed in the basement of a private house. The scheme is quite simple, so the well is cheaper than the well.

If power outages occur in your area, it is recommended to install a water tank in advance. The volume depends on the number of tenants, but the more the better. As for artesian wells, they are too rare in a private house or country house.

Central water supply system

At central system sewerage and water supply there are a lot of pluses. You do not need to spend money on the pumping station and the units themselves. Also, you do not need a storage tank for liquid. As for the purity of the supplied water and its pressure, these indicators will be taken care of by the organization that provides water resource for objects. Also, an enterprise can be a state type, in simple words- ZhEK. In this case, the sewerage and water supply system may work unstably: additional bills for pipe repairs, rust, low pressure.

The photo shows a large-scale system that provides water to an entire microdistrict.

When choosing a centralized sewerage system, you do not have to deal with digging trenches for pipes, creating a well, etc. You need to send an application to an organization that works in your sector. After obtaining a permit, work begins: special equipment prepares trenches for pipes, laying is carried out, meters are installed.

Important: before contacting such an organization, you need to study the reviews. If the water is supplied to other houses clean, without pressure drops, then you should choose centralized network, in other cases, you will be laying pipes and creating a sewer system with your own hands.

Charting

To make the scheme correct, you must have the skills of drawing and mathematics. If there is no experience in this matter, then it is better to turn to professionals who make plans.

So, you are ready to lay the water supply and make a sewer system with your own hands. You have studied the area and know what type of water supply is right for you. The next step will be the scheme - this is one of the most important points in creating a sewerage system in a private house, cottage or country house.

The schema must contain the following elements:

• collectors;
• filters;
• boilers;
• pumps;
• pipe size;
• pipeline path;
• distances between elements.

What is the most important thing in a diagram? Of course, this is piping. They can be connected in two ways: using a collector or in series. As for the first method, separate pipes go from the collector to consumers in a private house or in the country. The main advantage of installing a collector is a uniform pressure in all areas of the building. There are also disadvantages - high cost due to the large number of pipes.

Scheme of the pipeline with a collector.

A consistent method of connecting sewerage and water supply is recommended for small cottages. This scheme contains the main pipeline equipped with tees for each water consumer. If there are too many consumers in a private house or in the country, then the pressure indicator will constantly fall.

Construction with main piping.

Circuit example

You can study the features from the video and photo, consider the scheme where the pipe with water leads to the treatment system. This is done to ensure that consumers receive liquid suitable for consumption. Behind the treatment complex is a tee that distributes water flows to different consumers. The pipe that will supply hot water goes to the heating element, and the cold pipe is connected directly to the collector.

simple circuit allows you to understand how the water supply system works for a private house and for a summer residence.

Next, you need to put shut-off valves on the lines to consumers. Elements are mounted from the collector. The "hot" pipe goes from the heater to a separate collector designed for hot water. After it comes the piping of the building.

How is the installation and wiring

The differences between internal and external piping correspond to the difference between hidden and open wiring. If external wiring is selected, then the pipes will go through the house, in the case of a closed one, the elements will be placed inside the decoration of a private house and its walls. Also today you can make a semi-hidden version, in which the pipeline is installed in the box. They can be pasted over or painted in the same color as the walls. Also, the box can be left completely unfinished.

The water supply scheme in a private house or in the country is the most difficult moment, since the scheme is drawn up individually for each object. The water supply must be properly connected to the sewerage system. You will have to work on the walls with your own hands if you need hidden wiring. The fluid flow rate of each water intake point and the power of the well are the two main indicators that must be calculated before starting the process.

In addition to videos and photos, the advice of experienced builders always helps in the work:

• Shut-off valves should be evenly distributed throughout the system, which will come in handy in an emergency to quickly shut off the flow of water.
• It is best to fasten pipes in a private house or in the country with a threaded connection.
• Fittings, fixtures and splitters must be the same if they are installed in the same system.
• You can pass the walls in a private house with the help of gaskets that protect the material from corrosion, damage, abrasions and other adverse factors.
• There are drain taps throughout the system, when mounting them, make a slight bias towards the elements. This feature is needed so that the liquid does not accumulate in the pipeline.
• Buy fittings, seals, gaskets, tapes, fasteners and other items with a margin. If everything is the same in the system, then in the event of a breakdown, you can immediately replace the part.
• The fewer bends, the better. Each of them reduces the pressure in the sewerage and pipeline system in a private house or in the country.

Polypropylene pipe welding

Polypropylene elements are considered the most reliable of the pipes for giving. Polypropylene pipes are welded on the machine. The process is specific, so you should read the following instructions when welding polypropylene pipes:

1. We need to get segments, for this we need to cut the pipes with special scissors.
2. Welding points should be marked and cleaned with an alcohol wipe.
3. Next, select a suitable nozzle for polypropylene pipes, set the desired temperature and start the unit.
4. We are waiting for the heating of the welding machine, after which it is possible to push the segments of the house of marks onto the welding nozzles. It is not necessary to rotate the pipes.

The welder looks like this:

soldering of polypropylene pipes

Pipeline Care

The secret to the efficient and stable operation of the sewer along with the pipeline is simple - breakdowns must be eliminated immediately after they are detected. If the break in the pipe is small, then a rubber gasket can temporarily solve the problem. Also, in emergency situations, cold welding saves. Got a fistula? We make drilling and screw in the bolt (only suitable for new pipes).

Do-it-yourself installation and wiring of plumbing in a private house

Do-it-yourself plumbing in a private house can be carried out from a central water supply or from a well (well). The principles of its creation, the main components of the system in each of these cases do not actually differ.

Choosing a wiring diagram

There are two ways to supply water to consumption points, and the choice of a do-it-yourself water distribution scheme in a private house depends on the parameters of the system, as well as on the intensity of water consumption (permanent or periodic residence, number of residents, etc.).

serial connection

Such a connection is also called a tee. Faucet, shower and other points are connected in series. This method requires the use of fewer materials (pipes, fittings, etc.), therefore it is cheaper.

The disadvantage of a serial connection when distributing a water supply system is the likelihood of a decrease in pressure at the most remote points with the simultaneous use of several water intake points.

collector connection

A collector (or parallel) connection is the organization of a collector (or two collectors - hot and cold water supply), to which the lines leading to each water intake point are connected. To implement such a scheme, more pipes will be required, but its principle of operation allows for stable pressure.

Tee and collector water distribution schemes in the house

There are additional nuances when choosing the principle of water supply. Do-it-yourself installation of a water supply system in a private house can be done in two ways:

• "Deaf" lines ending in a dead end (stub). Such a plumbing scheme in the house is more economical, however, when hot water is supplied, it can create some inconvenience - when opening the tap, you must wait a certain time until the liquid reaches the plug, and only after that hot water will appear in the tap.
• Circulation closed lines are more practical and convenient, however, the implementation of such a project will require not only more pipes, but also a special circulation pump.

Experts recognize the combined option as the most rational, in which the “blind” distribution of cold water is combined with a hot water circulation line.

The main nodes of the scheme

The water distribution scheme in a private house, more precisely, that part of it that is responsible for supplying water to the house, consists of the following main components:

• pumping unit for a well or well,
• nipple (adapter),
• anti-backflow check valve,
• pipeline,
• filtration equipment (one or more different filters depending on water quality),
• stop valve,
• accumulator,
• pyaternik (fitting) for connecting the main elements and devices (pressure gauge, pressure switch, pipes).

The sequence of the water supply scheme

In order to visualize how water is distributed in a private house with your own hands, you can consider the course of communications from the source to the end point.

1. An individual water unit (well or well) is equipped with pumping equipment, the choice of which is carried out according to the following principles:

• for deep artesian wells, only submersible pumps can be used,
• for narrow channels and casing pipes- only surface aggregates, including, and pumping stations,
• in other cases, the choice between submersible and outdoor equipment is made depending on specifications specific models and operating conditions.

2. The pipeline that brings water to the house is usually laid underground. The depth of the trench is usually chosen taking into account the depth of soil freezing in a given region. As an additional protection against freezing, communications are supplied with a heat-insulating layer.

Conducting water supply to the house from a well with a caisson

3. The entry point of the pipeline into the house deserves special attention.

• Firstly, the hole for the pipe is made with a large margin - a gap of at least 150 mm on all sides. This avoids deformation and destruction of communications if, over time, the wall begins to sag or deform.
• Secondly, a small section of the pipe, located between underground and protected ground communications and internal wiring in a warm room, is in the open air. In this place, the risk of freezing of the pipeline is highest, so good thermal insulation is required.

4. The hydraulic accumulator and control devices are usually installed in the basement, basement or on the first floor near the entry point of the pipeline into the house. Purely technically, it would be more correct to place such equipment in the high point, however, in terms of practicality and usability, the lower levels are more suitable. It is only necessary to take into account the need to raise water to upper floors when setting the pressure switch.

The hydraulic accumulator is designed to stabilize the pressure in communications and prevent frequent inclusions(and, accordingly, rapid wear) of pumping equipment.

The control and monitoring unit includes a pressure gauge, a pressure switch and a dry-running switch, which prevents air entrapment and the formation of air locks in the system when the water level in the well or well decreases.

5. Filter systems are completed, depending on the need, with devices for:

After that, the plumbing is done in a private house with your own hands according to the chosen scheme. For a collector circuit, it might look like this:

• Immediately after the accumulator is a tee along with a stopcock. The tee divides the flow of water into two directions - to the house and for other needs (watering, washing the car, etc.);
• A deep filter is connected;
• Next comes the tee, from which the distribution of water pipes in a private house is divided into a pipe for cold water, which immediately goes to the cold water collector, and a pipe through which water will go to a boiler or other water heater for heating. After heating, the water is sent to the hot water collector.

In the photo, the water distribution scheme in a private house

Important: When installing water supply in a private house with your own hands according to the collector scheme, it is necessary to install shut-off valves at each point of water consumption.

Pipe selection

Communications diameter

When conducting plumbing in a private house with your own hands, a correctly selected pipe diameter will ensure cost-effectiveness at the installation stage of the system, as well as avoid unpleasant noise when water moves through communications.

To calculate the parameters of lines supplying water to consumption points, the starting point is the total length of each line:

• for a branch with a length of less than 10 meters, pipes with a diameter of 16-20 mm can be used,
• for branches about 30 meters - with a diameter of 25 mm,
• for the longest lines over 30 meters, pipes with a maximum diameter of 32 mm are required.

Important: Particular attention should be paid to the choice of the diameter of the collector pipe. Insufficient value can cause malfunctions in the system.

The distribution of water in a private house from the collector is calculated based on the fact that each tap has a throughput of about 5 liters per minute. After that, it is roughly calculated how much water is taken simultaneously from all points at peak moments and the diameter of the collector is chosen:

• 25 mm for a flow rate of 30 l/min,
• 32 mm for 50 l,
• 38 mm for 75 l.

Pipe material

Laying a water pipe in a private house allows you to use pipes from various materials, each of which has its own advantages, disadvantages and features of operation.

If you decide to stop at polypropylene, it will be useful for you to know how to weld polypropylene pipes.

Read more about the difference between collector and tee plumbing schemes here.

Since you will need coarse water filters, we advise you to familiarize yourself with their types.

In order for the system to work flawlessly, it is important to know how to properly install plumbing in a private house with your own hands. This concept can include both the basic principles regulated by building codes and regulations, as well as some of the nuances and subtleties known to experienced craftsmen.

• Ideally, the pipeline should not pass through building structures, however, in practice, the creation of such a scheme is often impossible or impractical. If it is necessary to conduct communications through the wall, the pipe must be placed in a protective glass.
• Despite the fact that the owner of the house almost always wants to get the maximum free space and for this "press" the pipeline from the wall, between building structures and communications running parallel to them must be a gap of at least 25 mm for easy holding repair work. The contour of the inner corner requires a distance of 40 mm, and the outer 15 mm.
• If there are drain valves on the pipelines or the hydraulic accumulator, a slight slope is made in their direction.
• Most convenient way fixing the pipeline to the walls - these are special clips. You can choose single or double devices, the distance between them in any case should be about 2 meters.

When deciding how to make water distribution in a private house, remember that a well-executed internal water supply system has characteristic differences:

• Minimum joints and adapters. This improves the reliability and efficiency of the system.
• All connections are made in strict accordance with the installation technology of this particular type of pipe.
• The presence of valves or shut-off valves in critical areas of the system and at connection points.
• The minimum number of not too reliable flexible sections for connection (hose connections), which are most vulnerable to pressure drops.
What can be done from pallets for giving with your own hands

A good old tradition can be called rest in the country. In order for the rest to pass with maximum comfort, it is necessary to install a minimum number of engineering networks, which include an autonomous sewage or water supply system. Consider the features of choosing a pipe for water supply in the country.

1. Stationary and collapsible. Stationary are represented by a non-separable design, which is installed for the entire long period of operation. In turn, collapsible can be dismantled with the onset of cold weather. When creating a collapsible structure, it should be borne in mind that it should have good protection from mechanical impact.
2. For winter water supply, a stationary type of water supply is installed.

The type of pipes used depends on the type of water supply. For a prefabricated type of construction, pipes made of polymers are suitable, at the ends of which there is a thread. A flexible hose is also often used, which can be quickly twisted if necessary.

plastic pipes

The main classification of pipes can be called the type of material used in the manufacture. Recently, plastic has been used quite often in the production of pipes for domestic pipelines. The advantages of plastic pipes can be called the following points:

1. No deposits are formed. In the case of sewers, the high roughness of the inner surface causes blockages. Due to the peculiarities of the production method, the inner surface of plastic pipes has a low roughness index.
2. No corrosion on the surface even with long term operation determines that it is not necessary to carry out maintenance of the pipeline, as well as additional protection against high humidity.
3. Despite the fact that products of the petroleum and chemical industries are used in the production of this type of pipe, during long-term operation in environment no harmful elements are emitted.
4. Bacteriological safety is at the highest level.
5. If the service life of a metal structure is no more than one decade due to the fact that without special protection, temperature drops and high humidity lead to corrosion and destruction of the structure of the material. As practice shows, plastic options execution, subject to their deepening, taking into account the freezing of the soil and providing protection against mechanical damage.
6. The lightness of pipes determines the significant simplification of transportation and installation.

Another indisputable advantage can be called low cost

Hot and cold water

When designing a home supply system for cold and hot water, the following points should be considered:

1. For drinking cold water, it is recommended to purchase polypropylene pipes.
2. Polyethylene is suitable for hot water, as this material tolerates temperature increase better.

When creating a pipeline for hot water, you need to remember that significant heating of some types of plastic leads to an increase in plasticity.

HDPE pipes are widely used:

1. Water supply throughout the site.
2. Innings drinking water to the house.
3. Water supply for various buildings, for example, baths and pools.

A feature of the material used can be called the possibility of expansion under strong pressure. An example is the case of soil freezing: even if water freezes in the system, the pipeline does not burst.

However, there is a significant drawback, which is susceptibility to ultraviolet radiation. Therefore, it is necessary to provide for the protection of pipes from exposure to the sun.

Stainless steel and copper

A serious problem of metal can be called the appearance of corrosion on the surface during prolonged use without waterproofing. That is why they began to produce versions of copper and stainless steel. They are reliable and durable, can be used in the case of supplying cold and warm water, as well as draining wastewater. Often they are chosen by people who do not seek to save on work on the supply of water or drainage.

Despite a fairly large number of advantages, the pipes in question are rarely used today. This is related to the following points:

1. There is a high probability of deposits and plaque on the walls.
2. When conducting installation work welding work is required.
3. High cost, especially copper versions.
4. Large weight, which determines the difficulties in the delivery and installation work.
5. High insulation requirements to eliminate the possibility of water crystallization when the ground freezes, which leads to a breakthrough of the system due to liquid expansion.

For a suburban area, such pipes are recommended to be used only with careful isolation of the line. The cost of insulation, the complexity of the work carried out, the cost of the materials used determine that a system of stainless and copper pipes is a very expensive investment.

Metal-plastic pipes

Metal-plastic pipes are also quite popular among summer residents. Their peculiarity lies in the following points:

1. The structure is three-layer, each layer performs its task.
2. The inner and outer layers are polymer. This material withstands exposure to high humidity and temperature extremes, a low roughness index does not lead to blockages.
3. The layer between the plastic is made of aluminum. This metal has high ductility and is not affected by corrosion.

They are aesthetically pleasing and light weight. The ductility of aluminum and the properties of plastic allow some versions of metal-plastic pipes to be bent, which reduces the number of connections due to the absence of the need for rotary elements. However, the multilayer structure and the use of aluminum significantly increase the cost of the product.

What you need to know about PVC pipes

Under the concept of plastic pipes, many of their varieties are understood. There are a large number of varieties of plastic, each with its own special performance characteristics. Quite popular pvc pipes. They are optimal solution at the time of the creation of a water supply or sewer outlet. As previously noted, an increase in temperature can cause an increase in the flexibility index. That is why manufacturers indicate:

1. For cold water choose PVC.
2. For hot water only CPVC can be installed.

In addition, CPVC is also used for cold water.

Determination of nominal pressure

If metal pipelines can withstand a sufficiently large pressure indicator, then with plastic ones everything is a little different. When purchasing plastic pipes, pay attention to the nominal pressure indicator, which is denoted by PN. It is recommended to purchase PN 10 and PN16 for cold water, PN20 and PN25 are suitable for hot water. For hot, versions with a higher nominal pressure are installed due to a decrease in strength due to heating of the material.

What pipe diameter to choose

Another important indicator is the inner diameter. As a rule, for the main pipeline they choose with a diameter of 25-32 mm. This should be enough to reduce the pressure in the system. In the case when it is necessary to determine the exact indicator, a hydraulic calculation is carried out, taking into account the peculiarities of the operation of plumbing and other appliances, the power of the water supply source.

Summing up, we note the following points:

1. The choice by type of material is carried out taking into account the easiest way to achieve sealed joints. For example, steel pipes can connect qualitatively only a welder of the 4th category.
2. Polymeric ones are suitable for giving, as they have sufficient strength and do not collapse when water freezes.
3. When choosing, the likelihood of corrosion on the surface is taken into account.

When buying pipes, attention should be paid to their integrity. Quite often there is a situation when, due to improper transportation or storage, cracks and other defects appear on the surface, a curvature appears - all this can cause a decrease in the reliability of the pipeline being created.
