Older or shallow wells may use an above-ground jet pump to pull water from the well.

Submersible electric pumps that push water up are more common. They typically feature a sealed motor that is lowered into the well and has an above-ground power source.

The tank is a closed container for the pump to fill with water. As water fills the tank, the air within becomes compressed, usually through an air-filled vinyl bladder, until pressure is high enough to trip the pressure switch. When someone opens a faucet, air pressure in the tank will squeeze the bladder and force water out. When enough water is used to lower the pressure, the switch turns the pump back on and the cycle repeats. If the tank loses its pressure (its “pre-charge,” which comes with the tank from the factory), the pump must work overtime to keep the tank full.

While some water treatment systems get rid of several pollutants, there is not just one treatment system that can work for every application or water contaminant. It is very important to know what the ability of the treatment methods that are being considered, what impurities they extract, precisely what number of flow rates they will process, and what water pressures they will operate within. Your first step should be to contact the well water treatment experts at Griswold Plumbing. We will help you figure it out.
