Which submersible pump to choose?

I want to install a pump for a private house. Technically there is no understanding in a well or indoors. Do you need any installation skills or is it better to choose a suitable pump and find a specialist who will install it?

Good day, Sergey.

The choice of elements of an autonomous water supply system depends on the depth of your well, the distance to the house and the required installation performance.

For shallow wells and wells, it is convenient to use factory pumping stations that can raise water from a depth of up to 9 m. It should be borne in mind that every 10 m of a horizontal pipeline is equal to 1 m of a vertical section, so most often the unit is installed in a pit equipped next to water intake site.

With a significant distance of the source from the house, as well as with an aquifer depth below 10 m, we recommend assembling the system yourself. To do this, you need a deep (downhole) pump, a hydraulic accumulator, a pressure switch with a manometer and PND polyethylene pipes of the PN10 brand, designed for drinking water.

Centrifugal units such as Aquarius, Vodomet, Belamos, etc. have proven themselves in work. It is advisable to take a larger accumulator tank - in this case you will have a supply of water in case of a power outage. In addition, the pump will be turned on much less frequently, and this has a direct effect on its durability. There is no need to equip a pit for a system with a deep pump. It is enough to choose a unit with a pressure sufficient to supply water under the required pressure to the storage tank installed in the basement, boiler room or in the kitchen.

As for permits, they are not needed for an autonomous water supply system for a private house. Installation of the water supply system can be entrusted to specialists or to perform it yourself. Believe me, this is nothing complicated.
