Abstract: A water closet is provided with a device for limiting the amount of water discharged from its water tank during flushing. More particularly, the volume of water discharged from the tank is limited by low water level reached during flushing. The water limiting device has a tube inserted into the outlet water passage of the tank and through the normal valve seat of the typical ball or flapper valve member, and the valve member is seated atop the tube. In one embodiment, for use with an outlet valve unit having a generally horizontal valve seat, the bottom of the tube is tapered to wedge into telescopic relationship with the outlet passage and may, if desired, be fixedly secured to the normal overflow pipe of the outlet valve unit. In a unit having an inclined seat for receiving a flapper valve member, the tube has a cylindrical end portion telescoped into the outlet passage, and an inclined flange seated against the inclined valve seat. Below this flange is an annular seat which mates with a beveled mouth of the outlet passage. The tube seat may be resilient and sealingly engage the mouth with an integral annular gasket seated against the flange and the valve seat. An arm integral with the upper portion of the tube is secured to the overflow pipe and carries a pair of opposed fingers for receiving apertured ears of the flapper valve which is seated atop the tube. These fingers are comparable to the conventional fingers provided on the typical outlet valve unit. A variation has a rigid tube seat integral with the flange, for seating against the beveled mouth of the outlet passage, and a separate annular gasket is provided for seating between the flange and the valve seat of the outlet passage.
