What is a well pressure tank?

A well pressure tank is a steel tank, usually with an internal rubber bladder or diaphragm, that stores pressurized water from a private well pump. Compressed air on one side pushes water into the house, so the pump does not start whenever a tap opens. A pressure switch typically cycles the pump between settings such as 40 and 60 psi.

Why it matters to you

When the bladder fails or the tank loses its air charge, the pump starts and stops every few seconds, wearing out the motor and pressure switch early. At MyHappyHome™, well equipment is not part of a base plan; it is covered through the optional well pump add-on, priced at checkout.

Practical guidance

Watch the pressure gauge while a faucet runs: rapid clicking at the pressure switch, or a needle that swings quickly between settings, points to a waterlogged tank. Turn off the pump's breaker and drain the tank before checking the air charge at its Schrader valve, which is usually set about 2 psi below the pump's cut-in pressure.
