Choosing a pump to increase water pressure: 5 proven brands

The work of modern plumbing and household appliances is associated with the presence of constant pressure in the water supply system. So, for the stable operation of the washing machine, you need a pressure in the system of 2 atmospheres. And hydromassage showers and bathtubs will cope with their task only at a pressure of at least 4 atmospheres. At the same time, it is extremely rare to find such indicators in domestic water supply. You can correct the situation with the help of devices to increase the pressure in the water supply. What types of devices exist and how to choose the right one - read below.

Before choosing a water booster based on the technical characteristics and cost of models, you should inspect the quality of domestic water supply, decide what problems the installation of the device should solve, study the main types and principle of operation of the devices. So, low water pressure in the system can be caused not only as a result of clogged pipes and filters.

The two most common domestic water supply problems are:

Weak water pressure, in which it is impossible to use the bath, shower, washing machine;
The presence of water only on the lower floors (there is not enough pressure to “squeeze out” the water to the upper floors).

In the first case, buying a pump that increases the pressure in the water supply will be ideal. In the second, only a pumping station can increase the pressure in the system.

The water pump consists of a plastic housing and an electric motor, which, while rotating, pumps air, thereby increasing the pressure in the pipes.

The fundamental difference between a station and a pump is that the former has a special water tank that continuously accumulates liquid and distributes it through pipes using a pump. This allows you to increase the pressure. Regulates the switching on and off of the station (after filling the tank with water) of the pressure switch.

Booster pumps for cold water supply: types

There are several types of pumps for raising pressure in water supply pipes. The main differences in the models are related to their installation method, design features. Depending on the purpose, devices for hot water are distinguished, and separately for cold water supply, universal devices.

So, household pumps by action and operating modes are divided into:

Automatic;
Manual.

The automatic flow pump is distinguished by a sensor that regulates the operation of the device: the pump turns on as soon as the tap opens. Pumps with automation have a longer service life, because the operation of manual models must be constantly monitored (make sure that the pump does not overheat).

The pumps can be cooled with a dry or wet rotor.

If you want a silent pump, then you should choose a device with a wet rotor, in which cooling occurs due to the pumping of liquid.

There are also separate pumps for dewatering, which allow you to lower the groundwater level and avoid flooding.

Such pumps can be with an electric and diesel engine. Models with a double-acting piston system are considered the most effective for dewatering.

Hot water booster pump

The principle of operation of the booster pump for water supply and heating systems is that the device increases the pressure in the network, depending on the pressure in the water circuit.

Forced circulation of the coolant in individual heating or water supply systems requires the presence of a device for pressurizing and pumping the carrier from the heating source to the points of water extraction (battery, shower, washing machine, etc.).

A pressure pump for supplying hot water and stabilizing the operation of the heating system is installed on the water return pipe. Therefore, the pump installation scheme will look like this: accumulator-heater-receiver. At the same time, the pump to increase the pressure in the system should only be installed in a horizontal position. If the pressure at the inlet of the installation is higher than atmospheric, then a booster compressor is used to stabilize the operation of the gas column.

How to choose a high pressure water pump

The choice of a domestic pump depends on the existing average pressure in the pipes. It is worth remembering that a pressure pump can only be installed if there is at least a minimum pressure in the system. If the pressure is less than 1 atmosphere, then a pump pump is better suited for pipes.

In order to choose a booster pump that will effectively cope with its task, you need:

Measure the pressure in the pipes and decide on your own needs. If you need to increase the pressure by several atmospheres, then one device will be enough. At the same time, remember that a pressure of four atmospheres is considered the most suitable for a domestic city water supply.
Examine the technical characteristics of the model. The most important indicators of a pump for maintaining pressure in a water supply system are the maximum water supply and maximum pressure. The first shows how much water the pump can pump in a minute or an hour. The second is how much the pump can raise the pressure at the installation site (the indicator is extremely important for the owners of a two-story private house).
Consider the noise level that the pump produces (this is especially important for small apartments with little sound insulation), the operating temperature range (pumps operate most efficiently within 5-100 degrees).

When buying a booster pump, you should pay attention to its body: it must be made of aluminum or stainless steel, be free of visible damage (dents, scratches, holes).

The best pump to increase the water pressure in the apartment

When choosing a home pump to increase pressure, it is important to take into account user reviews and their recommendations. So, choosing a pump tested by the majority, you can protect yourself from unnecessary costs as much as possible.

Today, the most famous and well-established manufacturers of pumps for increasing pressure are:

WILO- a German manufacturer that makes universal pressure devices with high technical and operational performance;
UNIPUMP- a domestic brand, which is distinguished by affordable and high-quality products;
Comfort- a Russian manufacturer that provides a wide range of water pumping devices with various technical characteristics at affordable prices;
Grundfos- a company from Denmark that offers booster pumps that can maintain a continuous supply of water in water supply and heating systems (can be installed in systems with gas water heaters);

Water pumps at affordable prices can be found at the Chinese company Seaflo Pumps. Especially popular here is the 12 V electric pump, which is great for installation in apartments and houses with a mains voltage of less than 220 V. The SPRUT GPD 15-9A pump is well suited for individual water supply systems.

We install a pump that increases the pressure in the water supply

Unlike connecting to the water supply system of stations, domestic pumps are easier and faster to install. You can put a booster pump in an apartment, a private house, in the country. In this case, the main pump crashes into the pipe at the inlet to the system. This also applies to pumps that are installed to improve the head of the column.

In order to connect an intermediate pump, you must:

Turn off the water in the installation area of the device.
Drop the water. If there are no special taps on the pipe to remove water from the system, then you need to disconnect the pipes at the lowest point, at the junction, and drain the water with a hose.
Mark and cut the pipe so that you can insert a device between its ends. You can cut the pipe with a hacksaw for metal.
Attach nozzles and fittings to the ends of the pipe. Usually, mounting accessories are included with the pump.
Attach the device to the pipe.

The circulation pump must be installed in a natural position (the position for installation is indicated in the instructions for the device). According to the installation method, the pump can be vertical (retaining) and horizontal. If the installation is made by mistake, then the pressure booster may not work, quickly fail, or do a poor job.

A low pressure booster pump is the best device for creating and maintaining a constant, high pressure in water supply pipes. Today, there are many pumps, different in principle of operation, installation method. The choice of devices is determined by the needs of the buyer, the existing pressure in the pipes. Using the above recommendations for choosing and rating companies whose products have shown themselves well on the market, you can choose an effective and durable device!
