Abstract
A water saving device for a flush tank includes a floating body, a guide track on which the floating body is slidably mounted by a bracket, and a clip mounted to the guide track for snap fitting around a standpipe of the tank. The guide track is positioned so that the body is substantially directly above a flush valve of the tank, so that upon flushing the body will contact and forcibly close the flush valve to save water. The weight of the body is adjustable, as the body has an inner chamber for holding ballast and an inlet sealed by a removable plug. The guide track has breakoff segments at its bottom portion so that the track can be adapted to virtually any size tank. In another embodiment of the water saving device, the guide track is replaced by a small diameter tube through which the chain linking the flush valve and the flush lever attached to a flush handle is threaded. The body has a large tube attached to it which slidably fits over the standpipe.
