What is a well pressure tank and how does it work?
A well pressure tank is a critical component of a well water system. It stores water pumped from the well, helping to maintain consistent water pressure throughout your home. When the water is drawn from the tank, it creates a vacuum effect that activates the pump, which refills the tank as needed and ensures a steady flow of water from your taps.
The tank is typically equipped with a pressure switch that controls the pump’s operation. When the water level drops to a predetermined pressure, the switch activates the pump to refill the tank. Conversely, when the tank reaches the upper pressure limit, the pump turns off. This system allows for efficient water delivery and reduces wear on the pump by minimizing its operating cycles.
