Installing a water pressure pump

A pump to increase the water pressure installed in the apartment will save you from problems with low pressure

Many residents of the upper floors of multi-storey buildings are familiar with the problem of insufficient pressure in the water supply network, when it is not only impossible to turn on the washing machine or take a shower, but even wash normally. A similar situation sometimes occurs in private country houses, if there is little water in the well or there is a low-power pump.

The solution to such problems is pumps that increase water pressure.

What should be the pressure in the water supply

The norm of pressure for the city water supply network is considered to be 0.4-0.5 MPa. Its increase by only one and a half times is capable of breaking pipe connections and incapacitating plumbing. And a serious decrease leads to a lack of pressure sufficient for the normal operation of household and plumbing equipment.

In other words, if it drops to 0.1 MPa, you will not be able to do laundry, wash dishes in a dishwasher, heat water in a column and just wash in the shower. This happens quite often, not to mention the complete shutdown of water or such a low pressure in the network at which it does not rise to the upper floors.

For reference. The minimum required pressure for household appliances using water is 0.15-0.25 MPa.

As you can see, jumps in any direction from the norm can seriously poison life and deprive you of your usual comfort. Therefore, if such a situation occurs regularly, care must be taken to stabilize the water pressure.

In houses with centralized water supply, management companies should do this, but even if they work in good faith, the solution of such problems is not always available. For example, when there is simply not enough pressure in the city network for everyone due to outdated equipment of a pumping station or an increase in the number of consumers as a result of mass development.

Both residents of apartment buildings and owners of country houses can be helped out by pressure boosting pumps for water, independently installed in a house or apartment. But first you need to make sure that the cause of the pressure drop is not a blockage in the pipes or lime deposits on their inner walls.

Schemes of step-up installations

Unfortunately, the water pressure booster pump itself is not a panacea in all cases. If the performance of a well or well is not sufficient for your needs, or if the liquid does not reach the upper floors during peak hours, being dismantled by the lower neighbors, it will not help. But let's look at each option separately.

How to increase the pressure in the presence of water in the system

If there is water in the pipes, but it flows slowly, a special pump is inserted into the house network to increase the pressure. It is installed at the entrance to the apartment and, due to its compact size, takes up very little space.

Advice. When choosing a model, pay attention to what water temperature it is designed for. There are both pumps for cold and hot water, and universal devices.

High pressure water pumps can operate in two modes:

  • Manual control mode involves turning the device on and off manually. It will run continuously until you turn it off. This is not very convenient, since the equipment must be monitored to prevent it from overheating.
  • When operating in automatic mode The function of the switch is taken over by the water pressure sensor for the pump. When you open a tap or turn on a household appliance, it activates the pump, which stabilizes the pressure in the network. But if there is no water in the inlet pipes, the switch-on signal is not received, which will protect the device from damage when operating in dry mode.

Regardless of the mode used, the pump can be turned off when not needed. Water will simply flow through it without encountering obstacles. Since such a pump often has to be mounted in a bathroom, in a kitchen or other habitable room, the noise level coming from it matters.

It depends on how the device is cooled:

  • For models with a “dry” rotor, cooling occurs with the help of an impeller mounted on the shaft. They are highly efficient, but they make audible noise, so they are best installed in an isolated room.

  • The units with a “wet” rotor operate almost silently, in which cooling occurs due to the pumped liquid.

In addition to these design features, water pressure boosting pumps differ from each other in power, performance, pressure indicators, which must be taken into account when choosing. It is desirable that this be done by a specialist.

What to do in case of water supply interruptions

The water pressure stabilization scheme looks completely different when the supply is carried out intermittently. This happens when the productivity of an individual well is less than your needs, or with frequent rolling blackouts of consumers of centralized networks.

The way out of this situation will be the installation of a storage tank and, which increases the pressure in the network from the tank to the water points.

Note! Residents of the upper floors, who do not have enough pressure, are sometimes offered the installation of self-priming pumps. The instruction does not allow their installation without a storage tank, since in this case water is pumped out of the riser and its absence in the neighbors' apartments.

The scheme below works great if there is a nominal pressure in the system at least a few hours a day.

The system works like this:

  • During the hours of maximum pressure, water is collected in a container, from which there is a wiring to all consumers: taps, faucets, a washing machine, etc.;
  • A float valve is installed on the supply pipeline, which closes the water supply when the upper level is reached;

It is important. It is necessary to provide for an emergency drain of water into the sewer in case of failure of the valve, as well as another drain at the bottom of the tank to empty it for cleaning.

  • To ensure normal pressure in the house network, an automatic pumping station is installed at the outlet of the tank, the main elements of which are a high-pressure water pump and a hydraulic accumulator with a pressure switch;

  • When the tap is opened, the water level in the accumulator decreases, the pressure in the system gradually drops. When it reaches critical values, the automation is activated and the pressure switch turns on the pump that supplies water from the storage tank;
  • After closing the tap, the pump will continue to work until the normal pressure in the accumulator is restored, after which the relay will turn off.

Thus, there is a continuous supply with an optimal pressure, as long as there is water in the tank. It is automatically replenished during the hours of minimum parsing.

Popular manufacturers

In such an important matter as ensuring an uninterrupted supply of water at normal pressure to the house, the price of the equipment is not so important as its reliability and compliance with the stated requirements. Buying pumps from trusted manufacturers with an excellent reputation gives you confidence in their quality and durability.

We offer you a brief overview of brands that have proven themselves in our market:

  • COMFORT- Russian-made pumps at an affordable price, represented by a wide range of models, in which you can find devices of the required performance and pressure.

  • UNIPUMP- Another domestic brand, whose products are famous for European quality.
  • SEAFLO (FUAN AIDI ELECTRIC CO LTD)- 12 volt high pressure water pump from China. An excellent solution for installation in areas where there is no 220 volt network.
  • WILO- high-quality German equipment, characterized by high technical performance and long service life. Their main advantage is versatility, the ability to increase the pressure of both cold and hot water.

  • Grundfos (see)- pumps from Denmark, capable of both pumping water and ensuring its continuous circulation in heating systems.

Conclusion

Is it worth giving up the usual comfort if you can provide it yourself? The answer to this question is obvious, the solution to the problem is elementary - the installation of pressure-increasing equipment. The video in this article will give you more information on this topic.
