A well is the most common way to obtain groundwater for household use. A well is basically a hole in the ground, held open by a pipe (or casing) that extends to an aquifer. A pump draws water from the aquifer for distribution through the plumbing system.
The device, which connects to the plumbing, regulates the home's water supply. When the water pressure drops to a certain level, the switch senses more water is needed, and spring-loaded electrical parts make contact, turning on the well pump. When the pressure returns to a preset level and the well tank is filled, the electrical contacts separate, and the well pump turns off.
