Abstract: A toilet flush mechanism conserves water by offering a choice made by the direction of rotation of the flushing handle of either actuating a first lever initiating the discharge of a full tank of water or actuating a second lever initiating the discharge of a predetermined fraction of the water in the full tank, herein designated a mini-flush. A flapper valve controlling the discharge of water from the tank is opened by the actuation of either of the levers, is permitted to close in conventional fashion when the tank is empty upon first lever actuation and is closed by a downward thrust of a striker upon second lever actuation. A water level responsive device including a second float triggers the striker and acts independently of the ballcock valve and float which maintains the full level of water in the conventional manner.
