How to install and connect a pumping station to a well

A suburban area requires the arrangement of autonomous communications. Including water supply. More often, craftsmen prefer to mount mine wells. Their depth does not exceed 13 meters. The water mirror is often located at the level of 3-6 m. In this case, it is quite simple to bring water from the well to the house with a pumping station. The main thing is to comply with all the principles of installation and connection of equipment.

Device and principle of operation

Pumping equipment for lifting and supplying water to a house has several important working units. These include:

• Centrifugal pump (submersible or surface). It works as a suction device, which is responsible for constant pressure in the system.
• Storage membrane tank. He's a hydraulic accumulator. The reservoir is responsible for the pump on-off cycles when filling or emptying. The accumulator is divided into sections with a special rubber membrane, which changes its position and pressure in the tank when the water level in it falls or rises.
• Pressure switch. Allows you to maintain a stable indicator of atmospheres in the pipeline and storage tank.

The pumping station operates according to the following principle:

• After installing and turning on the equipment, the intake hose, equipped with a filter and a non-return valve, sucks liquid into the unit chamber. From here, water is directed to the membrane tank until it is full.
• As soon as the pressure in the accumulator rises to the extremely high, the pump turns off automatically. There is a constant supply of liquid in the tank.
• When you open a tap in the house, water flows out of the reservoir and enters the plumbing points. At this moment, the pressure in the tank drops to a minimum. This is a signal for the pump to turn on again and take liquid from the well.

When installing a pumping station with a submersible pump in a well or with a surface principle of operation, the equipment does not change. The difference lies only in the position of the unit itself relative to the source.

Advantages and disadvantages

For pumping stations mounted to wells, the following advantages are characteristic:

• The presence of a single block in which all working nodes are arranged. The equipment does not take up much space.
• Complete assembly and readiness of stations for installation. The master does not need to look for components, to assemble the entire system himself.
• Constant pressure in the system, exclusion of water hammer.
• The work of the water supply system in autonomous mode in the absence of electricity, if there is a tank with a volume of 50 liters or more.

The disadvantages of pumping stations include relative noise (which can be extinguished by a caisson) and the inability to raise water from a depth of more than 10 m. If necessary, you will have to replenish the station with a remote ejector.

How to choose a station

It is necessary to choose good equipment for the specific parameters of the well and the family's requirements for water supply, taking into account the following factors:

• Station performance. It should be slightly lower than the water filling indicators of the well. If the performance of the unit is higher, it will quickly pump out water from the source and will remain idle until the flow rate is restored again. There is also a high risk of burning out the station when it is idling. It is impossible to start up the equipment at a low flow rate of the source.
• Power. It is important to pay attention to this parameter if there is no desire to overpay for electricity.For a family of two or for simple watering, equipment with a power of 500-800 watts will be enough.
• Allowable head. Here you need to take into account the distance from the water mirror to the farthest plumbing point in the house. All horizontal sections of the pipeline must be summed up. Every 10 meters of the horizontal line is equal to 1 meter of head specified in the technical documentation for the equipment.
• Storage tank volume. The bigger it is, the better. For a family of 2-3 people, you can take a tank with a capacity of 40 liters or more.
• Accumulator material. There are stainless steel and steel tanks on the market. The former are more durable.
• The presence of additional protections, automation. Such functions make the station more expensive, but often save in case of unstable flow rate of the well or power drops.

The price of the equipment is important for many craftsmen. But she is not a decisive factor.

Installation and connection features

Before starting a pumping station to supply water from a well, it is important to choose the right place for it. Here you need to adhere to the following recommendations:

• The station is mounted as close as possible to the well. This allows for a good water intake without losing the power of the unit.
• An even base without distortions is taken under the station. Even if the equipment is installed on an Abyssinian well. Better if it is a concreted area.
• It is advisable to protect the equipment from the effects of atmospheric precipitation. Therefore, a caisson is being built over the station. It will also smooth out the noise during the operation of the unit.

Station connection diagram:

• Installation of equipment on a solid foundation. Most models have feet that are bolted to the concrete floor. This eliminates vibration of the device. Better yet, place a rubberized mat under the feet of the unit.
• Using a fitting, a water intake hose is mounted. One end is equipped with a filter. Once the hose is connected to the inlet, it is lowered into the water.
• If we are talking about a submersible pump, it is attached to special brackets in the well shaft itself. The clamps exclude the possibility of movement of the unit and its impacts against the walls of the source.
• It is important to install a check valve on the outlet pipe. The distance from the branch pipe to it is left about a meter. The outlet pipe is connected to the main line.

Before starting, the system must be filled with water through the technological hole. A dry station is never turned on. This could lead to equipment burnout.

First start

Arrangement of a well with a pumping station in the country or in a country house is a responsible task. Therefore, after filling the system, the master conducts a test run of the station. Here it is important to fix the pressure indicators at the time of turning on and off the equipment in order to adjust its indicators to optimal ones. Recommended values ​​for starting the station - 1.8-1.5 bar; to shut down the unit - 2.5-3 bar. If the optimal readings differ from the actual ones, you need to calibrate the pressure switch. This is done by rotating the adjusting screws. They have special markings indicating the direction for increasing or decreasing indicators.

Only after adjusting the pressure can the unit be started in normal mode. If the equipment turns on and off at the set values ​​normally, then the wizard did everything correctly.

Rating of the best pumping stations for a well

Among the stations on the market for a well, several models are recognized as the most optimal.
