ABSTRACT:
A device for controlling the discharge of water from a toilet tank, in either a full flush mode or a partial flush mode, utilizes an opening mechanism that produces the full flush in its normal condition and without need for any extraordinary manipulation. Shifting the operating handle inwardly, while rotating it in the customary manner, will produce a partial discharge of the contents. The device includes a biasing member, which engages a moving part of the valve assembly to exert a closing bias thereupon, but which does not unduly limit the movement of the valve plug so as to constrain it to less than a fully open position.
