Patent number: 4185336Abstract: A deenergized solenoid operated valve normally closes the drain line of a sink, basin, tub or toilet bowl, the valve thus serving as a stopper. When a pushbutton switch is closed, the solenoid is energized to retract the valve and open the drain, a flow responsive switch maintaining the solenoid energized until all of the water has drained from the sink or bowl. A float responsive switch will also energize the solenoid to retract the valve and open the drain if water accumulates from a leaky faucet. Whenever water is drained, the low pressure or vacuum that results produces an accompanying venting action. The invention may be used with a P or S-type drain connection and/or with a conventional stack vent, but does not require that any of these be employed.Type: GrantFiled: September 11, 1978Date of Patent: January 29, 1980Inventor: Lyle M.
