Connecting a pumping station to a well: rules for organizing autonomous water supply

Well drilling completed, what next? It is necessary to organize a water supply system that allows you to wash the dishes, take a shower, water the plants and connect household appliances. Connecting the pumping station to the well will help to solve the problem. However, for a positive result, you should know exactly how to do it.

We will tell you about how it is better to arrange automated water supply for a country house or your favorite summer cottage on the basis of surface pumping equipment. In the article we presented, technological rules and principles of circuit assembly are described in detail. Based on our tips, you can easily build a system with your own hands.

Features of the pump station

Autonomous water supply at the base of the pumping station includes a set of devices that ensure automatic flow of water into the house. In order to organize a comfortable autonomous water supply, it is necessary to choose a suitable pump unit, connect it correctly and configure it.

If the installation is performed correctly and the operating requirements are followed, it will last a very long time. The house will always have clean water under pressure, allowing the use of modern appliances: from the usual shower and washing machine to the dishwasher and jacuzzi.

The pumping station consists of three main elements:

• a pump that supplies water;
• accumulator, where water is stored under pressure;
• control unit.

The pump pumps water into accumulator (GA), which is a tank with an internal insert of elastic material, which is often called a membrane or pear because of its shape.

The task of the pumping station is to ensure a constant flow of water into the house at a sufficiently high level of pressure in the water supply system

The more water in the accumulator, the stronger the membrane resists, the higher the pressure inside the tank. When the fluid enters the mains water supply, the pressure decreases. A pressure switch captures these changes and then turns the pump on or off.

It works like this:

1. Water fills the tank.
2. Pressure rises to the upper set limit.
3. Pressure switch turns off the pump, the flow of water stops.
4. When water is turned on, it begins to decrease from the GA.
5. There is a decrease in pressure to the lower limit.
6. The pressure switch turns on the pump, the tank is filled with water.

If you remove the relays and the accumulator from the circuit, the pump will need to be turned on and off each time the water is opened and closed, i.e. Often. As a result, even a very good pump will break quickly.

Using accumulator provides owners with additional bonuses. Water is supplied to the system under a certain constant pressure.

All components and materials necessary for connection should be prepared in advance. They must match the size of the branch pipes of the existing equipment, adapters may be necessary for successful installation

Good pressure is needed not only to take a shower comfortably, but also to operate an automatic washing machine or dishwasher, hydromassage and other benefits of civilization.

In addition, a certain (about 20 liters) but necessary water supply is stored in the tank if the equipment stops working. Sometimes this amount is enough to stretch to resolve the problem.

Place of installation: convenient and safe

Choosing a place, it is necessary to take into account the technical characteristics of the device and the distance from the installation site to the water level. If it is large enough, the station is placed in a household room or in the basement.

It must be ensured that the following conditions are met:

• it was dry and warm enough;
• there was the possibility of installing sound insulation;
• free access to devices for regular maintenance.

High humidity, as well as freezing of water inside the device, leads to breakdowns.

If the equipment is delivered in the house, you will have to take care of sound insulation. The status and settings of the main nodes must be periodically monitored. Devices should be installed in such a way as to allow readings to be read without difficulty, to set up relays, etc.

The pipes with which the pump equipment is connected must be integral, so you need to buy communications with a good margin of length

When installing a pumping station at the mouth of a deep well, a caisson is used so that the devices are as close to the water source as possible. Caisson - This is a container, quite spacious, in which holes and units are provided for convenient installation of pumping equipment.

The station is placed in a house or in a caisson, for example, from concrete rings. The equipment must be protected from moisture and freezing, and the residents of the house - from the noise of a working pump

Finished products of this type are sold in specialized stores, you can choose the option that suits the size and configuration. They are made of plastic, metal, polymer-sand compositions. For independent arrangement of the caisson, the pit is deepened and expanded, bricked with walls, a durable cover is mounted on top.

If the equipment will be used only in the summer, for example, for irrigation, you can put it even outside the house. But for the winter the station will have to be properly mothballed

Often, instead of masonry the caisson nets are used, concrete rings are used, between which the joints are closed, and then waterproofing works are performed. In the resulting small room they put pumping equipment.

Depth of installation should protect the equipment deepened in soil from freezing even in the most severe cold. In the southern regions, one and a half to two meters will suffice; in the north, a four-meter deepening may be necessary.

Connection order: step by step instructions

Pumping stations are suitable for equipment with relatively deep intake openings. If the depth of the groundwater mirror is exceeded, the maximum value specified by the manufacturer of the equipment is used remote ejectors.

To install, perform the following steps:

1. Lay a trench connecting the well and housing.
2. Pipes are laid in it.
3. Mount the water supply (if it is missing).
4. Install the unit in the selected location.
5. The supply pipe is equipped with a filter and a check valve.
6. Connect the trunk to the receiving pipe.
7. Connect the unit to the water supply.
8. Connect the equipment to power.
9. Fill the tank with water.
10. Perform a test run of the station.
11. Check the joints.
12. Set up a pressure switch.

External Pipes water supply systems it is necessary to lay below the level to which the soil freezes. It is recommended to make a slight bias from the house to the well so that the water returns to the pump if it stops working. This will protect the device from overheating and breakdowns due to dry running, i.e. work in the absence of water.

The same protective function performs check valve, not allowing fluid to leave the pipe and go into the well. When connecting a surface pump equipped with an ejector, it is required to attach one more to the suction pipe, which is fed to the ejector.

This unit directs part of the incoming fluid to the base of the pipe through which the fluid enters, which greatly increases the productivity of the equipment. If used submersible pump, the work is done differently. It is attached to the suction pipe and suspended on a durable stainless steel cable.

The bottom end of the feed pipe should be equipped with a strainer so that sand and other impurities do not pollute the water and damage the equipment

Submersible pumps are conveniently attached to the finished tip. Such a device is mounted on the upper part of the casing. It is believed that sealing the well with the tip allows you to slightly increase its debit. So that the cable and cable do not get tangled, they are fixed to the pipe with plastic ties.

If a filter is already in the pump, they are limited to installing a check valve. The edge of the feed line of the surface pump should be at a height greater than a meter. This minimum distance is half a meter for a submersible pump.

Connections of the unit with pipes must be performed using American cranes; valves are used to block any section and disconnect it for repair without damage to other elements of the system.

It is recommended to put an additional coarse filter in front of the station, and after it a filter is mounted that ensures the purity of drinking water, removing unwanted impurities

Installed in the workout well filter eventually wears out, sand begins to leak through it. It is recommended to install an additional coarse filter at the inlet to the pump.

Power supply is provided by bringing a separate line to the equipment equipped with an automatic shutdown device, grounding must be taken into account. Before starting, the device is filled with water through the hole provided for this.

In this case, the pressure in the hydraulic tank must be:

• about 1.5 bar for a container of less than 30 l;
• about 1.8 bar for 30-50 liters;
• 2 bars or slightly less for a 50-100 liter tank.

Then the hole for filling the water is closed and the device is connected to the mains. You need to open the valve to bleed air. A few minutes later, water will flow from here. Otherwise, turn off the device and add a little more liquid.

To adjust the pressure switch, it is necessary to remove the housing from it in order to gain access to the screws used to configure the device

Repeat the inclusion to the device began to work in normal mode. Now need configure relay. For this, the GA will have to be emptied and then filled again. The indicators are set by rotating the corresponding screws.

Some valuable suggestions

Threaded connections must be tightened with a wrench and not with your hands to ensure the necessary tightness. For connecting valves, safety devices and pumping station it is better to use pipes whose diameter is slightly larger than the calculated one in order to compensate for the load increased due to the bends of the main.

The recirculation line will protect the pump and increase the water pressure in the system. To install the return line you need a tee

To protect the pump from idle, a recirculation line can be installed. To do this, put tees on the supply and suction pipes and connect the loose pipes to the return line.

A crane should be installed on it to control the intensity of the return flow. Such an addition will improve the pressure, but will slightly reduce the performance of the device.

A bracket can be used as the base for the pumping station, but it should stand flat on the shock absorbing pads so that vibration is minimal

The pump station is placed on a perfectly flat base equipped with shock absorbing pads. This will reduce vibration exposure and also reduce the amount of noise.

About once every three months it is necessary to check:

• condition of joints for leaks.
• condition of filters for timely cleaning.
• relay settings for their correction;
• tank status to identify leaks.

If the pressure level in the hydraulic circuit does not correspond to the required level, it is easy to pump it up using a compressor or pump. On large tanks, a nipple connection is provided for this. If fluid flows from the hole, it means the inner membrane is torn and needs to be replaced.
