Abstract: A water conservation device for use in toilet tanks which have a valve movable between an open and a closed position. The valve is connected to a flush linkage which draws the valve to the open position upon activation of a flushing lever. The water conservation device consists of an elongate body having a first end and a second end. The first end of the elongate body is indirectly linked to the valve. The second end of the elongate body is indirectly suspended within the toilet tank, such that the elongate body is disposed at an angle to the valve. As the elongate body pivots, the weight of the elongate body pulls the valve into the closed position.
