The tank fills with water and presses against a rubber bladder pressurized with air, which fills and empties in response to system pressure. The bladder breaks or leaks and no longer maintains system pressure and needs to be replaced.

This valve can be manually released (warning: hot temperatures!) to bleed off pressure/air. This valve fails when the spring breaks or gets soft and must be replaced.
