A water closet having two operational modes, one for a partial flush and the other for a full tank flush, utilized in conjunction with a bowl trap fill meter tank which reduces water consumption. A two position actuating linkage utilized in conjunction with an auxiliary float provides positive partial or full tank flush operation dependent upon the directional movement of the flush lever handle by an operator. A bowl trap fill meter tank disposed in the flush tank is utilized for refilling the toilet bowl trap, reducing the amount of excess water normally wasted in conventional flush tanks during flushing and refilling of the tank and bowl. The flush actuating mechanism includes a selectively pivotal ball stopper trip arm which when moved in a first direction pivots to raise the flush ball stopper for a conventional full flush operation and in a second direction raises the ball stopper while releasing a ball stopper return mechanism, such that the ball stopper is returned to the closed position before the flush tank is emptied. The bowl refill tube found in a conventional flush tank is diverted into the trap meter tank which is filled each time the tank is flushed. A second conduit…
