Staying outside the city, in a summer residence, has additional difficulties, since there are not centralized communications everywhere. Residents of the periphery improve living conditions in a cottage or house so that it does not differ from urban comfortable housing. One of the points of a comfortable life concerns the constant availability of sufficient water. In this case, special equipment will help - a pumping station with your own hands. By self-installation, you can save your family budget.

The device and principle of operation of the unit

The majority of wells in suburban areas have a depth of up to 20 m, which is optimal for installing automatic equipment. With these parameters, there is no need to purchase a submersible pump, an automatic control system or an intermediate tank: directly from the well (or well), water flows to the points of analysis. To ensure the correct connection of the pumping station, you need to figure out what it consists of and how it works.

The main functional units of the station are the following equipment:

  • A centrifugal pump that lifts water and transports it to the house.
  • Hydraulic accumulator that softens water hammer. It consists of two parts, separated by a membrane.
  • Electric motor connected to pressure switch and pump.
  • A pressure switch that monitors its level in the system. If the pressure drops below a certain parameter, it starts the motor, if there is an excess of pressure, it turns off.
  • A pressure gauge is a device for determining pressure. With its help, adjustments are made.
  • Water intake system equipped with a check valve (located in a well or well).
  • The line connecting the water intake and the pump.

Using this formula, you can determine the maximum suction depth: the diagram clearly shows which measurements must be taken for this

The most common version of a pumping station is a hydraulic accumulator with a surface pump mounted on top and a unit that includes a pressure gauge, pressure switch and protection against dry running

As you can see from the table, the cost of pumping stations can be different. It depends on power, maximum head, throughput, manufacturer

Before installing the pumping equipment, it is necessary to purchase all functional parts according to the parameters of the well and the water supply system.

How to properly supply water to a private house from a well or a well, you can learn more from the material:

Self-assembly of the pumping station

Determining the installation location

At first glance, there are quite a few places for mounting equipment - this is any free corner in the house or outside it. In fact, everything turns out to be different. However, only a well-thought-out installation of a pumping station guarantees its full-fledged operation, therefore, certain conditions must be observed.

Installation conditions:

  • proximity to a well or well ensures stable water suction;
  • the room must be warm, dry and ventilated;
  • the location should not be cramped, as maintenance and repair work will be required;
  • the room should hide the noise that the pumping equipment makes.

One of the options for installing the pumping station is on a shelf specially attached to the wall. The installation room is a boiler room, boiler room or utility room.

It is difficult to meet all the conditions, but it is advisable to adhere to at least some. So, let's take a look at some suitable mounting locations.

Option # 1 - room inside the house

A well-insulated boiler room on the territory of the cottage is an ideal area for installation in case of permanent residence. The main disadvantage is good audibility with poor soundproofing of the room.

If the pumping station is located in a separate room of the country house, then it is best to arrange the well directly under the building.

The material on how to make a borehole water supply system will also be useful:

Option # 2 - basement

An underfloor or basement can be equipped for the installation of a pumping station, but this should be considered when designing. If there is no heating in the room, and the floors and walls are not insulated, you will have to spend a lot of effort to prepare it.

A well-equipped basement is perfect for installing a pumping station. During the laying of the pipeline in the foundation of the house, a hole should be made for communications

Option # 3 - special well

Possible option with a couple of pitfalls. The first is the difficulty in maintaining the required level of pressure in the house, the second is the difficulty of performing repair work.

When the pumping station is located in a well, on a specially equipped site, the pressure level should be adjusted, which depends on the power of the equipment and the parameters of the pressure pipe

Option # 4 - caisson

A special site near the exit of the well is also suitable for installation, the main thing is to correctly calculate the depth of its location. The required temperature will be created by the heat of the earth.

And outside, you can decorate the well caisson by building a decorative wooden well. Read about this:

The pumping station, located in the caisson of the well, has two advantages: complete noise insulation and protection against freezing during frost

In the absence of specially designed places, the unit is installed in public places (in the hallway, bathroom, corridor, in the kitchen), but this is an extreme option. The loud noise of the station and comfortable rest are incompatible concepts, therefore, it is better to prepare a separate room for the installation of a pumping station in the country.

Pipeline laying

The well is usually located near the house. In order for the pumping station to work properly and without interruptions, it is necessary to ensure the unhindered flow of water from the source to the equipment, which is located in a specially designated place. For this purpose, a pipeline is being laid.

Low winter temperatures can cause pipes to freeze, so they are buried in the ground, preferably to a depth that is below the freezing level of the soil. Otherwise, the line should be insulated. The works boil down to the following:

  • digging a trench with a slight slope towards the well;
  • device in the foundation of the hole for the pipe at the optimal height (if necessary);
  • pipe laying;
  • connecting the pipeline to pumping equipment.

During the arrangement of the highway, one may encounter such a problem as the presence of high-standing surface waters. In this case, the pipes are mounted above the critical level, and heat-insulating material or a heating cable is used to protect against cold.

Advantages of polyethylene pipes and fittings over metal counterparts: no corrosion, ease of installation and repair, low price (30-40 rubles / r.m.)

This diagram of the installation of the pumping station shows a variant of pipe insulation above the level of soil freezing.

The best option for thermal insulation of external water pipes is a hard "shell" of expanded polystyrene (thickness - 8 cm) wrapped in foil

For thermal insulation of pipes that are laid above the freezing level of the soil, an inexpensive and environmentally friendly material is often used - basalt-based mineral wool.

Outdoor work

On the outside of the polypropylene pipe, we fix a metal mesh, which will serve as a coarse filter. In addition, a non-return valve will be needed to ensure that the pipe is filled with water consistently.

There is an opportunity to purchase a ready-made hose with a check valve and a coarse filter, but one equipped with your own hands will cost much less

Without this part, the pipe will remain empty, therefore, the pump will not be able to pump water. The non-return valve is fixed using a coupling with an external thread. The end of the pipe equipped in this way is placed in the well.

The coarse filter for the supply hose is a metal mesh with a fine mesh. Without it, the correct operation of the pumping station is impossible.

After completing these steps, you can start refining the well head.

Equipment connection

So, how should you properly connect a home pumping station so as not to face technical inconsistencies in the future? First of all, we install the unit on a specially prepared base. It can be brick, concrete or wood. To ensure stability, we screw the legs of the station with anchor bolts.

For the installation of the pumping station, special legs-stands are provided, however, to give additional stability, the equipment must be fixed with bolts

By placing a rubber mat under the equipment, unnecessary vibrations can be damped.

For more convenient maintenance, the pumping station is installed on a base as high as a conventional table, made of durable material - concrete, brick

The next step is to connect the pipe coming from the well. Most often, this is a polyethylene product with a diameter of 32 mm. To connect, you will need a coupling with an external thread (1 inch), a metal corner with an external thread (1 inch), a check valve with a similar diameter, a straight American cock. We connect all the parts: we fix the pipe with a coupling, we fix the American with a thread.

One of the check valves is located in the well, the second is mounted directly to the pumping station. Both valves serve to protect the system from water hammer and ensure the correct direction of water movement

The second exit is intended for communication with the water supply network. It is usually located at the top of the equipment. Connection pipes are also made of polyethylene, as it is an inexpensive, ductile, durable material. The fixation takes place in a similar way - using an American and a combined coupling (1 inch, 90 ° angle) with an external thread. First, we fasten the American woman to the station exit, then we mount a propylene coupling into the tap, and finally fix the water pipe in the coupling by soldering.

To completely seal the joints, they must be sealed. Traditionally, a linen winding is used, a special sealing paste is applied on top of it.

After you have connected the pumping station to the water intake and water supply system, you need to check the quality of its work.

We carry out a test run

Before starting the station, it must be filled with water. We let water through the filler hole so that it fills the hydraulic accumulator, lines and the pump. We open the valves and turn on the power supply. The engine starts and water begins to fill the riser until all air has been removed. The pressure will rise until the set value is reached - 1.5-3 atm, then the equipment is automatically turned off.

In some cases it is necessary to adjust the pressure value. To this end, remove the cover from the relay and tighten the nut

As you can see, it is not difficult to install a home pumping station with your own hands, the main thing is to follow the installation instructions.

A simple wiring diagram for a pumping station for a private house

To solve the problem of water supply, many private home owners use pumping stations.

These devices are now available for sale ready-made or can be purchased separately. Moreover, it is within the power of each person to complete the installation of a pumping station in his home. The main thing is to know what elements this apparatus consists of, how it works, how to start the pumping station and where it is better to install it.

Features of the

The pumping station is capable of supplying water to the water supply system of the house, as well as automatically maintaining the specified pressure in it. Due to this, it is possible to make the water supply network branched, making it easier to connect various household appliances to it, for example, a boiler, a shower cabin, a washing machine, and so on.

The pumping station is a pump, accumulator, automation, filter, pipelines. A well or a well is suitable as a source for water intake. You can use water from open reservoirs or other reservoirs. In the event that water is taken from a river, lake or pond, it must be used only for household needs or irrigation. It is better to take water from a well or well for analysis, the results of which will show whether it is household or drinking water.

Basically, in the sections, the depth of the wells is about 20 meters, which is the optimal value for the installation of automatic equipment. These parameters make it possible to deliver water to the sampling points without any additional equipment.

The pumping station operates in cycles, each of which is divided into two stages. When the pump turns on, water rises from the source, fills the system and the hydraulic tank. This happens until the pressure exceeds the upper limit. As soon as this happens, the pressure switch turns off the pump and water stops flowing.

At the time of opening the taps or using water-consuming equipment, water flows from the accumulator tank. The fluid from the hydraulic tank will be consumed until it reaches the lower limit. Then the pump turns on again and raises water into the hydraulic tank.

It must be ensured that the number of cycles per hour does not exceed the maximum permissible number of starts for the pump in use.

The advantages of the pumping station are obvious:

  • provides autonomous water supply in the house
  • allows to increase the efficiency of the water supply system
  • allows for safer operation of equipment and pipelines
  • allows you to make some supply of water and supply it, even if the power supply is turned off

  • provides a stable water pressure and maintains a constant pressure
  • increases the service life of appliances and household appliances connected to the water supply system
  • reduces energy costs and equipment wear
  • makes it possible to choose a place for the installation of the unit
  • has compact dimensions and low weight
  • easy to mount.

Place of installation

Typically, the pumping station is assembled in a heated room. The ideal place would be a boiler room with well-equipped soundproofing. There are other options for how to install a water station. Often it is placed in the basement or basement, but subject to heat, sound and waterproofing. You can also use a special box - it is placed in a subfield with a hatch that provides access to equipment.

A platform is used to locate the station in the well. It is mounted below the level of freezing of the earth. In this case, the structure of the well should be insulated from above. But this way of locating a water station is characterized by problematic access to it.

You can also build a house for a pumping station or place equipment in an extension. If this is a separate building, it must not only be insulated, but also heated in cold weather.

Self-made installation can significantly reduce the cost of equipping the pumping unit. Depending on the type of source, different water station connection schemes are used.Correct installation depends, among other things, on small elements such as oil seal, non-return valve, filters, etc. They can improve and make the operation of the pumping equipment longer.

Pump station start-up

In order to start the pumping station in operation, it is necessary to completely fill it and the supply pipeline with water. For this, there is a special filler hole in the body. Pour water into it until it appears. We twist the plug into place, open the tap at the outlet to the consumers and start the station. At first, the water comes with air - air locks come out, which were formed when filling the pumping station. When the water flows in an even stream without air, your system has entered the operating mode, you can operate it.

If you have poured water, and the station still does not start - the water does not swing or comes in jerks - you need to figure it out. There are several possible reasons:

  • there is no check valve on the suction pipe, lowered into the source, or it does not work
  • somewhere on the pipe there is a leaky connection through which air is leaking
  • the resistance of the pipeline is too high - a pipe of a larger diameter or with smoother walls is needed (in the case of a metal pipe)
  • the water mirror is too low, there is not enough power.

To exclude damage to the equipment itself, you can start it by lowering the short supply pipe into some container (water tank). If everything works, check the line, suction depth and check valve.
