ABSTRACT:
A double valve construction selectively provides a full flush or a partial flush from the tank of a toilet. The apparatus, which may be utilized to modify existing toilet water closets, includes a hollow cylinder with a first valve on its lower end engageable with a first valve seat on an upper end of an outlet from the tank. The upper end of the cylinder defines a second valve seat and a second valve is engageable with the second valve seat. As an operating handle is selectively moved through a first range of travel, it disengages the second valve from the second valve seat for a partial flush and as the operating handle is moved through a second range of travel, it disengages the first valve from the first valve seat for a full flush. The volume of water utilized in a full flush is adjustable, and a mechanism is provided for holding the first valve in its open position until a full flush has been achieved.
