  • Water saver valve
    Patent number: 7077376
    Abstract: The present invention relates to a valve designed to be in series with a toilet water supply line and the inlet of a toilet tank so that water which is flowing into the tank must flow through the valve. The valve includes a shutoff spool that is actuated by an intensifier piston. When the water volume exceeds the tank capacity due to a failure of the float valve in the toilet supply tank, the shutoff spool is actuated by the intensifier piston allowing flow to the toilet to be blocked.
