How to properly install and connect a water supply pumping station

With the help of a pumping station, it is possible to organize a full-fledged water supply system - the pumping equipment will maintain a constant pressure in it. This will allow you to use any household appliances - a boiler, a washing machine, because the pressure in the system will be constant. The service life, as well as the quality of the device's operation, depends on how correctly the calculations are carried out and the place for installation is chosen. The pumping station does not like moisture, which accelerates the formation of rust and shortens the service life of the unit.

The process of installing and connecting the pumping station

Pumping equipment can be assembled by hand, you can buy a ready-made unit and quickly connect it to the pipes. Main elements:

  • submersible or surface pump that lifts water from a well or well;
  • a hydraulic accumulator, in which the pressure is regulated, after which a signal is sent to the sensor to turn on or off the unit;
  • a relay that performs the function of turning the device on and off;
  • pressure gauge, by which you can visually control the upper and lower pressure limits;
  • a system of pipes through which the pumping station is connected to the water supply.

For long-term and safe operation of the device, purchased models have a system of sensors that prevent idle operation, as well as overheating of the structure. Self-made pumping stations are rarely equipped with such devices, so the work has to be regulated independently.

The advantage of a pumping station with a storage tank over an automatic pump is that it turns on less often, thereby increasing the working resource. An automatic pump turns on whenever a tap is turned on in the house.

Pumping stations can perform several functions:

  • supply water from the well to the storage tank;
  • pump liquid from the tank to the house;
  • increase the pressure in the pipeline.

The strapping scheme in these cases is different, but in general terms it is similar. Installation of pipes and manifold is carried out according to the instructions attached to the equipment.

If water is needed only at certain times of the year, it is recommended to use a temporary scheme for the installation of the pumping station. For permanent use, you need to make a stationary base, but for this you need to find a place.

Seat selection

The pump station must be installed on a solid, level surface.

The basic rule for choosing an installation site is that the room must be dry and warm. During operation in a cold, damp place, condensation forms on the body and hydraulic tank. It gradually destroys the metal. The station must be installed in a heated basement, shed or caisson located below the freezing level of the ground.

A concrete pad is made to secure the body. This is especially important if the pumping station will be located in a caisson next to a water source. Based on the technical characteristics of the equipment, the most suitable place is selected. If the pump can lift liquid from a depth of up to 7 meters, its installation in a caisson will be justified, since the depth of the chamber itself is usually more than 2 meters. This saves power if the distance to the water surface is 9 meters.

You can build a place directly in the well, but in this case it will be difficult to repair or maintain the device.It must be done in such a way that at least one person can fit near the station, and can go down there along the metal brackets.

A caisson or well is the best choice of installation location if the appliance is very noisy. It is not advisable to place it in the house, since the sound of the motor will be heard anywhere in the house.

Model selection calculations

In order for the unit to cope with the task at hand, its power is calculated depending on the number of plumbing devices, as well as water points in addition to plumbing - a washing machine or dishwasher, a boiler, a heating boiler. It matters how many residents are in the house and how much water is consumed during rush hour - in the morning and in the evening, when everyone is at home.

If the water intake point is located far from the house, such a parameter as the water pressure or the height of the water column is important. Each meter vertically equals 10 meters horizontally. For example, the depth to the water mirror is 4 meters, and the distance to the house is 30 meters. In this case, 4 + 3 = 7 meters of water column should be created by the station.

One of the main parameters of the station is productivity. This indicator must be less than the productivity of the well, otherwise the pump will pump out all the water and may burn out due to dry running.

Power is of secondary importance. First, you need to check the performance of the well. To do this, make a complete pumping out of water and measure its volume.

The well in the area may have a great depth, which is beyond the power of a surface pumping station. In this case, it is better to choose a submersible pump and connect it with a pipe system to a diaphragm tank located on the surface. Such equipment pumps water from any depth and does not create noise. Difficulties may arise when the unit breaks down, since it will have to be lifted to the surface, so it is better to immediately buy a high-quality pump with a long service life (on and off cycles) or install a pumping station with an ejector.

Tools and materials

To connect the pumping station to the water supply system, a polypropylene pipe with a diameter of 32 mm is used. One end is connected to the unit, the other is lowered into the well. A mesh filter is put on the end of the pipe so that sand and dirt do not get into the motor. You also need to provide a check valve that prevents the fluid from draining back into the well.

For work you will need:

  • couplings for arranging pipe bends;
  • wrenches in a set;
  • a rubber mat to reduce the impact of vibrations on the concrete pad, which can deteriorate over time;
  • American crane to connect the station with pipes - inlet and outlet, you need 2 pieces;
  • flax and paste-sealant for pipe joints.

It is necessary to calculate the length of plastic pipes with a margin, since unforeseen obstacles and a foundation may arise on the way to the house, which will require the use of more materials. It is recommended to make as few turns and bends of the line as possible, as this reduces the performance of the water supply system. The straighter the pipes are laid, the fewer problems with operation and maintenance, the more economical the consumption of materials for inspection and inspection chambers in places of turns.

Installation technology according to different schemes

Pumping station connection diagram

The connection diagram of the pumping station to the storage tank is rarely used, since the technology has many disadvantages. Hydraulic accumulators with a rubber membrane inside are used. They allow you to make a supply of water, but the pressure in the system does not drop, unlike large-volume tanks. If you still need a large tank, you can connect the pumping station to a container with water using a polypropylene pipe with a diameter of 32 mm.

Installation of equipment begins after laying the water pipes and preparing the site for the unit.

  1. Secure the station to the rubber mat. Screw the legs with anchor bolts, preferably not cheap Chinese ones, as they quickly break from vibrations.
  2. Connect the American faucet with the lower outlet from the body, then through a metal corner with a pipe, at the end of which put a filter and a check valve.
  3. Connect the second upper outlet with water pipes. Here you will need a second tap, a coupling, which is soldered to the pipe for tightness.
  4. Check equipment operation. To begin with, fill the line that goes into the well, the accumulator and the pump with water. Connect to the network.

After the water flows into the house, you can fill the street water supply with soil, having previously insulated it with stone mineral wool or an electric cable.

Errors and how to fix them

Mistakes most often occur due to unnecessary savings. The absence of filters or protection sensors reduces the service life of the pumping station, since solid particles create friction in the internal parts and they wear out faster. Water in the ground can change its depth due to the movements of the earth's crust. If the sensor against dry running is not installed, the motor will burn out from overheating.

Do not cover the station with insulating materials - they have a very low thermal conductivity, so the motor will not be able to cool down and will burn out. Pipes in the ground located above the freezing level must be covered, otherwise in winter traffic jams will form, which can cause the line to burst.

If there are a large number of turns and bends in the water main, the pipes should be of a larger diameter so that the performance of the station and the water supply system does not suffer.

It is necessary to connect pipe sections with high quality, otherwise a leak appears at the joints over time. Some of the vibrations are transmitted to the pipes, which reduces their tightness.

To extend the life of the rubber membrane, before turning on and operating the pumping station, you need to adjust the air pressure in the accumulator and in the membrane. If there is little air, use a bicycle or machine pump for priming. Otherwise, the rubber will stretch unnecessarily and will soon tear or lose elasticity.
