Abstract
A commode flush valve for providing short and adjustable flush cycles. The flush valve includes a valve seat around the upper end of a discharge pipe for a tank, and a body pivoted to it. The body has a peripheral valve seal to bear against the valve seat to close the flush valve. A cup beneath the valve seal has a perforation near its top for exit of air, and an opening at its bottom to enable water to flow therethrough. A removable insert is fitted in this opening with an orifice sized to regulate the rate of flow water therethrough, and perforations to enable substantially all water to drain from the cup where the valve seal rests on the valve seat.
