What Is a Well Pump and Pressure Tank?
How a well works is dependent on two vital components—the well pump and the well pressure tank. Think of a well pump as the heart of your well water system. Its purpose is to draw water from the well and either push it up a pipe or pull water through suction. The well pressure tank is designed to store water, send water into your home, and regulate water pressure so it flows through your taps at an even rate.
The well pump and pressure tank work in tandem to supply water to your home. When a faucet is turned on, the air pressure in your well pressure tank pushes water toward your tap until the pressure drops to a certain level. This activates the tank’s pressure switch, which signals the well pump to turn on. When the faucet is turned off, the pressure tank refills with water, increasing the air and water pressure inside the tank. Once the right amount of water and air fills the tank, the pressure switch signals the well pump to turn off.
