A dual mode flush valve assembly selectively operable in a full or partial flush mode for use with a toilet flush tank assembly including a flush actuator movable between a first and second position interconnected to a buoyant flush valve movable between an open and closed position, the dual mode flush valve assembly comprising a flush valve actuator assembly movable between an upper buoyant position, an intermediate full flush position and a lower partial flush position in combination with a flush valve control assembly movable between a first and second position disposed to selectively engage the flush valve actuator assembly when in the first position such that when the flush actuator is in the first position the flush valve actuator assembly is in the upper buoyant position and the buoyant flush valve is in the closed position, when the flush actuator is moved from the first to second position for less than a predetermined period of time moving the buoyant flush valve to the open position, the flush valve actuator assembly moves downward to the intermediate full flush position to engage the flush valve control assembly in the first position whereby the flush valve actuator assembly is held in spaced relation relative to the buoyant flush valve to provide the full flush mode and when the flush actuator is moved from the first to second position for more than the predetermined period of time moving the buoyant flush valve to the open position and the flush valve actuator assembly to the second position the flush valve actuator assembly moves downward to the lower partial flush position to engage the flush valve moving the buoyant flush valve to the closed position to provide the partial flush mode.
