ABSTRACT:
A flush valve system is disclosed which sequentially fills and drains the water of the flush tank so as to eliminate wasted water. The flush valve system has a secondary, weighted float and a primary float which controls the water inlet valve that, in turn, controls the entry of water into the flush tank. The secondary float operates to prevent the entry of water into the flush tank until the water in the flush tank is substantially drained, and prevents overlapping operations of filling and draining a flush tank that might otherwise cause water to be wasted.
