(54)	Reduced water consumption flush toilet having a common actuation mechanism that controls a water valve by a first flexible cable and controls a waste valve by asecond flexible cable

(57) A reduced water consumption flush toilet includes a bowl assembly defining a bowl and a discharge opening at a lower end of the bowl. The toilet additionally includes a valve mounted to the flush toilet for selectively opening and closing the discharge opening of the bowl assembly and a water valve for selectively delivering a source of flush water to the bowl. The toilet further includes a common actuator assembly for controlling both the waste valve and the water valve. The actuator assembly is coupled to the water valve through a first flexible cable and coupled to the waste valve through a second flexible cable. The actuator assembly includes a lever that is movable from a first position to an intermediate position and from the intermediate position to a second position such that in the first position the waste valve closes the discharge opening and the water valve is in the closed condition, in the intermediate position the waste valve closes the discharge opening and the water valve is in the open position for adding water to the bowl, and in the second position the waste valve opens the discharge opening and the water valve is in the open position for flushing the bowl.
