How is a water supply pumping station for a private house and summer cottage

The arrangement of a private house begins with the installation of communications. One of them is water supply and sewer. Typically, clean water is supplied from a well or well. In order for the water supply process to be uninterrupted, they resort to installing a pumping station. The complex allows you to provide the house with water around the clock and have a constant supply of it. The device of a pumping station for a domestic water supply system is quite simple.

Purpose and principle of operation

The home pumping system is designed to lift water from a depth of 8 meters and supply it to all plumbing points in the cottage. The system works according to the following principle:

1. A water unit installed between two sections of the pipeline and connected to a power outlet pumps liquid from a source into a special storage device - a hydraulic accumulator.
2. When a certain pressure in the tank is reached, the pump turns off. The water supply has been completed.
3. As soon as the user turns on the tap in the house, the liquid enters the desired plumbing point.
4. At the same time, the pressure in the accumulator drops and the switch-on relay is triggered. The pump replenishes the water in the tank and then turns off.

The cycles of the station are constantly repeated due to the pressure drops in the tank.

Basic elements of a home pumping station

The operation of a pumping station for a private house is based on its main elements:

• pump - surface or submersible, depending on the model of the unit;
• storage tank - it's also a hydraulic accumulator or hydraulic tank;
• filters - they are installed independently, since the elements are not included in the kit;
• automatic control unit;
• a check valve, responsible for the timely supply of water to the house when the pressure in the tank rises.

Installation of filters allows you to protect all working elements of the equipment from malfunctions in the presence of fine suspended matter in the water: sand, clay, etc.

Types and classification

All pumping systems for private use are distinguished in several categories. There are two types of equipment according to the type of suction:

• With built-in ejector. Designed for lifting and transporting water into the house from a depth of up to 8 meters. The model is relevant for installation on a well. Stations with a built-in ejector are working very loudly. It is better to install them in a special caisson, and not in the house.
• With a remote ejector. Equipment capable of lifting water from a depth of 8 to 50 meters. Optimal for use with a well. Works quietly.

By the type of water supply and supply:

• Equipment with a separately installed tank. Provides a constant supply of water. The tank takes up a lot of space and there is a risk of flooding the room in the event of a problem with the drive. With a low water pressure, the tank does not work, you have to install an additional booster pump.
• Hydraulic station. The control of the filling of the tank is carried out by the accumulator and the membrane (usually, in the section on the diagram, it often looks like a diaphragm). The tank has a compact size. The use of hydraulic equipment at a shallow depth of water rise is relevant.

It is believed that the reservoir of the hydraulic station is more reliable.

By the type of pump, the following systems are distinguished:

• Submersible. The unit is deepened into the water.Experts believe that this type of equipment is more durable and easier to install and maintain.
• Superficial. The pump is located on land. The intake pipe is lowered into the source. Surface pumps have a simpler control system.

There are also special borehole and well stations. The former have a more powerful submersible centrifugal pump, which is demanding on water quality. Well equipment can withstand the presence of impurities in it.

How to choose a pumping station

When choosing pumping equipment for a private house, you need to be guided by the following criteria:

• Power. It's important not to go too far. Equipment that is too strong depletes the source and is costly. A weak station will not provide a supply of water for the house. The average power rating of equipment for private use is 900-1500 watts.
• Water suction depth. Some models are capable of pumping water only from a level up to 8 m - meaning the distance from the surface of the earth to the liquid mirror in the source.
• Hydraulic tank volume. For a family of 3-4 people, a capacity of 25-50 liters will be enough.
• The presence of additional protection. Many models are equipped with overheating systems. They prevent damage to the pump in the event of a drop in the water level in the source.
• Pump body material. Plastic is considered optimal. It dampens noise, is durable and environmentally friendly.

The list of selection criteria also includes the equipment manufacturer. Popular are Gilex, Metabo, Pedrollo, Grundfos and Gardena. Good equipment cannot be cheap. On average, you will have to pay for the pumping system from $ 500.

Installation steps

Installation of equipment for pumping water from a well / well takes place in several stages:

• The fully assembled system is equipped with filters.
• Connect the unit to the suction line and be sure to monitor the grounding.
• The membrane tank and the system are filled with water, the pressure switch is adjusted.
• Include a pumping station.

To damp vibrations, a special anti-vibration gasket must be laid under the equipment. The room or caisson for the installation of the station must be insulated so that the water in the tank does not freeze in winter.

Important points in service and operation

The basic principles of system operation allow extending its service life and avoiding complex repairs. They boil down to the following:

• The room, the caisson and the pipeline before and after the pump must be insulated, otherwise the water will freeze in the system in winter.
• If living in a house is not expected in winter, the water from the hydraulic tank and the pipeline must be drained before the onset of frost.
• The correct operation of the pressure switch should be checked regularly (once a month and after each conservation of the system).
• It is important to clean the coarse filters regularly. The frequency of the operation depends on the degree of contamination of the water in the source.

Clogging the filter will cause the pump to idle and burn the equipment.

Advantages and disadvantages of pumping stations

The main positive aspects of the pumping station are:

• ease of installation and operation: the systems are delivered pre-assembled;
• providing a private house with uninterrupted water supply in an autonomous mode;
• protection of equipment from overheating and idling;
• moderate operating noise, which is muffled by the correct positioning of the system; some types of equipment generally operate silently;
• long service life provided that the unit is used correctly.

The relative disadvantages include the cost of pumping equipment and the need for preliminary settings before starting.

The cost of pumping stations

The price of a water supply pumping station for a private house varies depending on the manufacturer, capacity, volume of the storage tank. On average, in Moscow and the region, they ask for 2,000-3,000 rubles for low-performance models. More powerful models will cost an order of magnitude more - from 4,000 to 10,000 rubles.If we are talking about a complex multistage station with strong technical characteristics, the price for it will start from 15,000 rubles and more. How much to pay for a reliable model of the unit, the master decides, depending on the needs of the family and the budget.

Installing a pumping station in a suburban area eliminates problems with the smooth operation of a well or well. As a result, living in a country cottage becomes no less comfortable than in a city apartment. If you have your own sewerage system, you do not have to pay for sewerage.
