ABSTRACT:
A two flush modality toilet composed of a bowl, a tank connected with the bowl wherein the tank is connected to a water supply, a conventional flush modality for flushing solid waste from the bowl, and a urinal flush modality for flushing liquid only waste from the bowl, wherein the urinal flush modality includes: a bowl valve in the form of a pop-up stopper, pop-up seat and pivot ball assembly at the low point of the bowl; a bowl valve control for selecting between open and closed states of the bowl valve, a passageway for directing liquid waste from the bowl into the sanitary drain; and an auxiliary flush control for supplying a limited quantity of flush water from the tank into the bowl to provide restoration of the trap water in the bowl after a urinal flush modality liquid drainage of the bowl has occurred. A foot pedal selectively operates the bowl valve, wherein when in an open state all the liquid in the bowl is drained. Upon release of the foot pedal, the bowl valve is returned to the closed state. A limited amount of flush water from the tank is then delivered to the bowl to restore the trap water.
