How Drinking Water Pumps Work


If we live in a city, we probably don’t care much how the water we use gets to our house, we just turn on the tap and have it.

But what if we live a few miles from the city? The picture changes. The water supply here is in every household independent of the neighbors, and each household has its own well from which it draws water. In addition, each household has its own electromechanical system to get the water from the well into the house. The heart of each system is a pump, and the most common types are submersible pumps.

The most effective solution is to insert the pump in the bottom of the well so that the pump, instead of lifting the water, pushes it upwards. A typical submersible pump has a long cylindrical shape that fits into the well. The lower half consists of a sealed motor connected to the overload power supply and controlled by cable. The other half of the pump is made up of a series of impellers, each separated by a diffuser that directs the water to the mains.

In modern installations, the well installed outside the house is connected to the plumbing system via a pipe that extends under the floor to the basement, as shown in the picture below. This horizontal pipe connects the well thanks to a connection known as a useless adapter, the purpose of which is to allow access to the pump line and through the top, while the water is directed from the pump to the pipe system.

Submersible pumps are known for their reliability and often perform their functions for 20 or 25 years. They can also be used in shallow wells, where ingredients such as sludge, sand, algae and other contaminants can shorten the life of the pump.
