Anyone who lives in an apartment house, and even on the upper floors, faced with the problem of low water pressure at the tap.This is especially true in the summer, when the water may not reach the apartment.Meanwhile, all modern appliances that use tap water require a stable high pressure of at least 2 atmospheres.This is especially true shower and Jacuzzi.When a head of a smaller wash will be simply impossible.According to the standards, the pressure should be no less than 4 atmospheres.How to increase the pressure in the water?After all, apartment - this is not a private home, it is not possible to make your own water with a powerful pump.Yet there is a solution.

Causes of low pressure in the water system

In many cities and towns the water supply network were built in the 70 - 80-xx years of the last century.If they periodically repaired surface, the underground part of it is repaired only in an emergency.For this reason, no matter how powerful pumps were not installed at the pumping stations, pressure in the end-user is still falling.To cope with this problem the ordinary citizen, who lives in an apartment building can not but reduce its impact on themselves quite powerless.

second reason, it is old or clogged pipes in the house.This problem is solved easily.Residents should initiate repair networks of its management company.Replacement of a new plastic pipes, pressure is likely to solve a problem in the water.The third reason - it blockages in pipes and fittings in the apartment itself.This is achieved by simply replacing the valves and other components, as well as flushing pipes.If
network in the house new and pipes in the apartment are varied, but the pressure is still there, it is considered to be the first cause.In this case, the repair can not wait until retirement, and the water is needed now.It may have to decide.

Which hardware can increase the pressure in the water

Today industry produces several kinds of pumps to increase the pressure in the water.Consider some of their options.

pumping station

This is a set of equipment to raise the pressure in the water system.Most often, it is used in the organization independent water in a private home, since the power of the installation is to suck water from a great depth of the well.Its principle of operation is based on the fact that with the help of an electric motor coupled with the piston, the air is pumped out of the accumulator, similar to a big balloon.

In the vacuum directs water from a well or borehole.If you install such a system in the apartment, it is likely that you will be with water, even if before that it does not reach you, but your neighbors are unlikely, even if they had it before.The installation of such equipment should be coordinated with all interested individuals and organizations.In addition, due to its size, install it in the apartment will be problematic.

If you have received all approvals, it will be necessary to determine the place where all the equipment will be installed.It has a fairly large size, and place it in a city apartment is very troublesome.It is necessary to allocate a corner in the bathroom for him.Complete pumping station includes: a motor with air cooling system, the accumulator, which can be different sizes depending on the volume of coarse and fine filters purification, various sensors and electronic control system unit.Moreover, the unit for such wiring requires installation tube.That is why, pumping stations installed in private homes for lifting water from deep wells and wells, rather than in apartments, where there is no room for them.

Pump station - is able to deliver the water , even where it was not.

centrifugal pumps to increase the pressure in the water, and their installation

If tap water is running at least a trickle, the need for bulky pumping station no.It will be enough to buy a small device that is installed directly into the pipe at the entrance to the apartment.Most current pumps have two operating modes: manual and automatic.In manual mode, the pump must always be switched on and off independently.In automatic mode, the inclusion of the equipment is made at the opening of one of the taps in the apartment.It provides a special device called a flow sensor.It gives a signal to switch only when the movement of water through the pipe.If it is not, for example, when the tap is closed, the pump stops.This device protects against burnout at work dry.Therefore, when choosing a machine, you need to stop on such a variant.

Since for any positive work in accordance with the laws of thermodynamics, the system gives off heat, the pump must somehow be cooled in order not to burn.By way of cooling devices centrifugal pumps for raising the pressure in the water can be divided into:

  1. Pumps with dry rotor.The impeller located on the motor rotor, air is blown on the motor housing, which it cools.Distinctive features of these pumps are not strong running noise and high efficiency.
  2. pumps with wet rotor.Water flowing through a pump cools the engine itself.Quiet operation - their main advantage.

When buying a centrifugal pump, it is necessary to draw attention to the fact that some of them are universal, while others are intended for hot or cold water.

To connect any of these pumps in water supply apartments, need to arm themselves with a special soldering iron pipe and related tools.at the apartment entrance Crane overlap and after the cut piece of pipe, which should coincide with the length of the path length of the flow of water through the pump and flow sensor.Next solder the ends of the pipe trimmed proper connection fittings and bolted to her pump with a sensor.Connections thoroughly compacted special sealing tape.Pumps include network and open the tap.It can work both in manual and in automatic mode, increasing the pressure in the entire plumbing apartments.

The above types of pumps are used to pressure increase in the entire apartment water system.However, many experts now believe that if there is water in the apartment, but the pressure is not enough, for example, for the boiler, the pump can be installed directly in front of him.This decision was not unreasonable.After all, under normal pressure of cold water, hot is virtually absent, as through a storage tank water heater, it can not get through.How to increase the pressure in the water just at the entrance to one of the appliances?To make it even easier than in the entire apartment.It cut into the tube with their soldering is not required at all.You can do the usual flexible connector.

Install the pump to increase the pressure with a flexible reinforcement

As mentioned above, set the pump to increase the pressure in the water in front of a household appliance is easy.Consider the steps to do it.

1. Learning the technical characteristics of the device, which we want to work to normalize.In them, we need to pay attention to the allowable maximum pressures.

2. Buy a centrifugal pump to increase the pressure in the water, which has a thread on inlet and outlet for the flexible liner.Not to be confused with centrifugal pumps for the heating system.They have a similar appearance, but carving them much more.When buying pay attention to the pressure characteristics.They should not significantly exceed the allowable for the device to which you plan to connect.This point is very important, as a violation of this rule may result in equipment damage that may void your warranty.

3. To buy an additional pump ball valve and flexible connection required length.Carving on the appliance and the hose should be the same.If the pump is more, you need to choose the appropriate adapter.Do not forget about fum-tape for insulating compounds.

4. Coming home overlap in the running water faucet entering the apartment, and then unscrew the flexible liner, which leads from the pipe to the device.This should be just the input hose.

5. Find the place where the pump is installed.More often than not it is attached to the wall with two screws vertically or horizontally.fastening method is usually written in the instructions to the pump.So, it is necessary that all hoses before him without getting out the kinks.If this is not possible, get a long liner.

6. Mark up on the wall for the pump mounting points, drilled holes and insert the plastic anchors.

7. At the pump welling flow sensor.This is done usually at the output.For information: on the pump and on the sensor flow is marked with arrows that indicate the direction of water flow.So to mix input and output is not possible.Plug in the wiring leading from the sensor is inserted into the socket on the control unit.It's a box, located on the power cord, which controls the entire operation of the pump.It also has a switch, via which the pump can be converted in a manual or automatic mode.When installing the threaded connections do not forget to create the isolation of the sealing tape.This will prevent leaks and re-dismantle all connections.Furthermore, all connections are established rubber gaskets, which are bundled pump.

8. The device is attached to the wall with screws so that there were no significant vibration.Warning: attach the pump is only permitted as described in the instructions to him.Otherwise, the system can exit from the bearing.If this is a bathroom, and the water can get to the pump housing, it has protection against this possibility, but do not overdo it.Cooling should be carried out in normal mode, so you can not close the film or something else opening the casing of the impeller.

9. Connect the pump inlet to the water pipe through the shut-off valve, and the output from the device, the pressure in which to improve.Everything is assembled.Turn it into an electrical network normal plug with earth terminal.

10. Put the pump switch in the "0" position and open the valve on the water pipe entering the apartment.We look at all the connections.If you see stains, eliminate the flow by adding or replacing the sealing film, pre-blocking valve.If the stains do not have, then turn on the pump in manual mode, after opening the hot water tap or shower.Hearing the noise of the pump should not be afraid.It is normal for devices with dry rotor.We notice if water flow is increased.If the pressure is increased and your problem is solved, then we check how the pump will operate in automatic mode.

11. Switch the toggle switch for automatic operation and open the valve.The device must earn himself once filled with water.At the close of the crane, the pump turns off.It should be noted that sometimes at very low pressure, the flow sensor may not work.In this case, the pump is transferred to a manual mode, but you just do not forget to turn it off when you close the tap in order to avoid overheating and failure.
