ABSTRACT:
A discharge valve closure of the type which has a bleeder port to permit the conservation of water by causing the closure to shut the discharge valve prior to the draining of all water from the water tank. The discharge valve closure features an adjustment which permits at least a portion of the buoyancy chamber to be pivoted about the axis of the closure to position the bleeder port at a selected angular spacing from its top dead center position. This adjustment allows the tank water level at which the closure shuts off the discharge valve to be adjusted.
