A flush toilet water valve assembly for connection to a water closet that has first and second open ended conduits that are selectively opened by valve mechanism to discharge water from different levels, and thus different water volumes, from the water closet to the toilet bowl. The first and second conduits intersect adjacent the lower end connection of the flush valve body to the discharge opening of the water closet. A valve mechanism within the valve assembly selectively closes off water passage through one or the other of the conduits in response to flush flow through the other conduit, preventing cross flow of water from one conduit through the other conduit.
