ABSTRACT:
An apparatus and method for conserving water during the flush cycle of a tank-type toilet. The apparatus includes a pivotally mounted lever arm having a water-fillable weight on one end and a toilet tank float engagement means on the other end. The water-fillable weight serves as a counter balance to maintain the toilet tank float in an elevated position to thereby hold the water inlet valve closed during the initial stages of the flush cycle. The apparatus also includes means for mounting the pivot mechanism in the toilet tank. The method involves slowly draining water from the water-fillable weight during the flush cycle so as to allow the toilet tank float to be lowered toward the end of the flush cycle and thereby open the inlet valve to refill the toilet tank.
