Abstract
An attachment for making existing flush tanks use less water mounts on the overflow pipe and has a valve operator for pushing the flush valve closed at an intermediate water level. The valve operator is controlled by a float which releases a latch allowing the operator to close the valve. The user may obtain a full flush by holding the flush handle down about 11/2 seconds. Provision is made for allowing the user to convert from a partial flush to a full flush simply by flushing again immediately after a partial flush is terminated. This feature utilizes the additional drop in water level below the partial flush level. The invention also includes an improved latch-valve operator relationship having side by side sections allowing a compact construction to give unlimited movement of the valve operator. One form of the invention requires only two moving parts to perform all the functions mentioned above. This is accomplished by a latch construction having two types of relative movement between the parts. Inward relative movement releases and closes the valve. Lateral relative movement allows reengagement.
