Domestic deep-water pump: installation and operation

Submersible pump acts as one of the main devices for supplying much-needed water to the house. Equipment should be selected, taking into account the parameters of the source of water supply, as well as the needs of a particular user. You can install such a pump either independently or by using the help of specialists.

Types of deep pumps

A deep pump, the installation of which you can be made without assistance, can be well, well or drainage. The first variety has the ability to lift water from a fairly impressive depth, passing it over long distances. Well pumps are designed for installation in a well and differ less impressive capacity. This affects not only the performance, but also the pressure. Drainage variety of pumps is used for pumping contaminated water from drainage wells, cellars and swimming pools.

Installation of well pump

If you chose a well pump, installation of such a unit will be within your power. The technology will depend on the location of the device. In order to make installation work on installation in the pump well to provide the house with water, it is necessary to lay a water pipe. He will connect the equipment that is in the well, with plumbing products installed inside the house. The master must take into account that the depth of the water pipes should be greater than the depth of freezing of the soil. This is an important aspect. If you decide to choose a well pump, the installation of this equipment involves bringing the electric supply cable to the well. With it, you can connect the equipment. The wire can be placed on the surface of the soil in a protective sleeve or with water pipes. If you decide to choose the latter option, then in this case the cable will be less exposed to technical influences. On the upper ring of the well, it is necessary to fix the bracket designed to hold the equipment. If the depth of the source is more than 30 meters, then for the convenience of extracting the unit it is possible to make a metal formwork. As for the less impressive depth, you can use a conventional bracket, to which the pump is fixed using metal cables.

Final work

A deep pump, the installation of which is done without the involvement of an outside specialist, must be connected to the water supply system. If the equipment is devoid of a special valve, which is designed to prevent the passage of water in the opposite direction, the device must be installed additionally. At the next stage, you can connect electricity. The cable must be fixed to the pipes that are located inside the well. Use for this you need an insulating tape. This manipulation will eliminate the damage that can disrupt the equipment. A deep pump, the price of which can reach 15,000 rubles, is lowered into the well to the required level and strengthened with the help of a holding device. The master has to control the first start of the unit. It is important to check the correct operation of the device and the maximum tightness of the existing connections.

Recommendations for the installation of the pump in the well

The deep pump (the price of the device varies depending on the functionality) can be installed in the well. This will require special equipment, the cost of which sometimes reaches 30,000 rubles. Initially, the master will carry out the wiring of the water pipe system in the well to the points of consumption. You will need to pipet the piping. A drainage pipe is fixed to the equipment, as well as a power cable. In the complete set with the unit there should be a scheme of connection of the deep pump.

Recommendation of the master

If you are not ready to carry out installation work independently, you can use the help of specialists. The cost of installing a deep pump can reach 7,000 rubles. It is worth remembering that a downhole pump is also not recommended to be used without a non-return valve, it must be installed on the equipment before the water supply is connected.

Installation advice

All pipes of the water supply system must be insulated with tape, which eliminates entanglement and damage. After the design can be prepared, it should be lowered into the well to the required level. The unit must be fixed on the head. This element is not only a holding device for the pump, but also protection against getting all kinds of objects, foreign debris and leaves. The head is also the link between the building water supply system and the pump itself. A sewerage system must be connected to it. The master must check how well the work is done. Only after this it will be possible to commission the device.

Accumulator connection

Automation for the deep pump will extend the life of the equipment. The accumulator accumulates a water reserve, and when the plumbing product is switched on, the liquid is expended from the tank, only after reaching the critical water level does the pump turn on. One-time connection of the equipment is able to meet the needs of users, and then refill the capacity. If you use a hydraulic accumulator, you will reduce the frequency of switching on the equipment, which will lead to an increase in the period of use. Automation for the deep pump reduces the number of pressure drops due to the use of several cranes at the same time. This approach will protect the system from hydraulic shocks that occur when the device is turned on. The accumulator can not be mounted without a pressure switch, it works when the minimum water level in the tank is reached. Repair of deep-seated pumps requires the production of much less often with this supplement. Install the pump into a well or a well is quite simple. As the main condition in this case is the correct selection of equipment and the advance preparation of additional materials, namely the check valve, connecting and additional electrical wires.

Recommendations for operating a deep pump

The deep pump for the well must not only be properly selected and installed, but also used according to the rules that are prescribed by the manufacturer. Before choosing and buying this unit, you need to get information about the voltage supply. This is important when choosing import models. Everything that comes from abroad corresponds to the industrial standards of the producing country. Thus, for German pumps, the permissible deviation in the supply voltage is from +6 to -10%. This rule should be taken into account, even in the event that the system of equipment has built-in protection functionality. The voltage surges will adversely affect the life of the engine. In this case, it is necessary to provide for the presence of adjustable voltage protection in the control cabinet for three-phase pumps. This is true for defective modes of operation. Choosing a deep pump for a well, you should remember that 85% of breakages occur because of the failure of the electrical part of the equipment. The main cause is the interturn closure of the stator windings. This can lead to a hydraulic overload. Such unpleasant moments can be avoided by setting current protection.

If the domestic deep well pump is used under improper conditions, it may be necessary to spend on lifting the pump and repair it. The price will be equivalent to the cost of the engine. Have to pay for the re-lowering of equipment, as well as putting it into operation. As practice shows, the final amount may be greater than the cost of the new unit.

Conclusion

If the cost of installing a deep pump, which was mentioned above, seems unacceptable for you, then such work can be done independently. However, one should take into account the fact that equipment may not be covered by the manufacturer's warranty in this case.
