What causes a pressure tank to lose pressure?

A common cause is a failed check valve. The check valve or foot valve prevents the well pressure tank from sending water back down into the well after it has built up with water pressure. Another very common issue is the pressure tank losing its captive air pressure.

How do you fix a waterlogged pressure tank?

  1. Turn off the power to the pump.
  2. Attach a garden hose to the drain on the tank.
  3. Open the valve and drain all the water out of it.
  4. Shut the valve.
  5. Flip the breaker or switch to turn the power back on to the pump.
