ABSTRACT:
A flush regulator selectively operable in partial flush mode or a full flush mode for use with a water closet including a water storage tank having a flush drain aperture formed in the lower portion thereof and a buoyant flapper valve disposed to selectively seal the flush drain aperture movable between an open and closed position by a flush handle movable between a first and second position to selectively control the flow of water through the flush drain aperture, the flush regulator comprising a buoyant flush assembly movably disposed within the water closet including a float chamber to control the buoyancy of the buoyant flush assembly and a dispensing chamber configured to operatively house a bleach/detergent therein such that when the flush handle is moved from the first position to the second position and released the float chamber engages the buoyant flapper valve in the open position to force the buoyant flapper valve to prematurely return to the closed position to operate in the partial flush mode and when the flush handle is moved from the first position to the second position and held in the second position the buoyant flapper valve is held in the open position to operate in the full flush mode and wherein when the flush handle is moved from the first position to the second position and released a portion of the bleach/detergent disposed within the dispensing chamber is dispersed into the water storage tank. Several embodiments are disclosed.
