Pump station: connection diagrams and do-it-yourself installation procedures

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

The device and principle of operation of the unit

The main number of wells in summer cottages has a depth of up to 20 m - optimal for the installation of automatic equipment. With these parameters, you do not 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 for lifting water and transporting it to the house.
  • Hydraulic accumulator, softening water hammer. It consists of two parts separated by a membrane.
  • An electric motor connected to a pressure switch and a pump.
  • Pressure switch that controls 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.
  • Pressure gauge - a device for determining pressure. With its help produce adjustment.
  • A 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 demonstrates clearly what measurements to do this

The most common version of the pumping station is a hydraulic accumulator with a surface pump mounted on top and a unit including a pressure gauge, pressure switch and dry run protection

As can be seen 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 the functional parts according to the parameters of the well and the water supply system.

Self-assembly of a pumping station

Determining the installation location

At first glance, there are a lot of places for installation of equipment - this is any free corner in the house or beyond. In fact, everything is different. However, only a well-thought-out installation of the pumping station guarantees its full operation, therefore, some conditions must be observed.

Installation conditions:

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

One of the options for installing a 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 comply with all conditions, but it is advisable to adhere to at least some. So, consider a few suitable places for installation.

Option # 1 - a room inside the house

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

If the pumping station is located in a separate room of the country house, then the well is best arranged right under the building

Option # 2 - Basement

The subfloor 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 great for installing a pumping station. During the laying of the pipeline, a hole for communications should be made in the foundation of the house

Option # 3 - a special well

A possible option having a couple of pitfalls. The first is the difficulty of maintaining the desired level of pressure in the house, the second is the difficulty of repair work.

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

Option # 4 - caisson

A special platform near the well exit is also suitable for installation, the main thing is to correctly calculate the depth of its location. The necessary temperature will create the heat of the earth.

And from the outside you can decorate the borehole caisson by constructing a decorative wooden well. Read about it: dekor / dekorativnyj-kolodec-svoimi-rukami.html

The pumping station, located in the well caisson, has two advantages: full noise isolation and frost protection during frost

In the absence of specially designated places, the unit is installed in common areas (in the hallway, bathroom, corridor, in the kitchen), but this is an extreme option. The station’s loud noise and comfortable rest are incompatible concepts, so it’s 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 unhindered flow of water from the source to the equipment, which is located in a specially designated place. To do this, lay a pipeline.

Low winter temperatures can cause the pipes to freeze, so they are buried in the ground, preferably to a depth below the freezing level of the soil. Otherwise, insulation of the trunk should be made. The work is as follows:

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

During the arrangement of the highway, you may encounter such a problem as the presence of high standing surface water. In this case, the pipes are mounted above a critical level, and thermal protection 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 / item m)

This installation diagram of the pumping station shows the option of pipe insulation above the level of soil freezing

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

For thermal insulation of pipes that are laid above the level of freezing, often use an inexpensive and environmentally friendly material - mineral wool on a basalt basis.

Outdoor work

On the outside of the polypropylene pipe we fix a metal mesh, which will serve as a coarse filter. In addition, a check valve is required to ensure that the pipe is stably filled with water.

It is possible to purchase a ready-made hose with a non-return valve and a coarse filter, but equipped with your own hands will be much cheaper

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

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

After completing these steps, you can begin to refine the wellhead.

Equipment connection

So, how should you connect the home pumping station correctly so that you do not encounter 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 support legs are provided, however, to give additional stability, the equipment must be fixed with bolts

If you place a rubber mat under the equipment, you can damp out unnecessary vibrations.

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

The next step is to connect the pipe coming from the well. Most often this is a plastic product with a diameter of 32 mm. For the connection you will need a coupling with an external thread (1 inch), a metal corner with an external thread (1 inch), a check valve with the same diameter, a straight American valve. We connect all the details: we fix the pipe with a sleeve, we fix the "American" with the help of a thread.

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

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

For complete sealing of the joints, their sealing is necessary. Traditionally, a flax 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, it is necessary 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 accumulator, lines and pump. Open the valves and turn on the power. The engine starts and water begins to fill the pressure pipe until all air has been removed. The pressure will increase until it reaches the set value - 1.5-3 atm, then the equipment automatically turns off.

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

As you can see, it’s not difficult to install a home pumping station yourself, the main thing is to follow the installation instructions.
