Abstract
A device to shut-off a water supply to a toilet diverts water from a toilet fill valve to a shut-off valve that has a housing that includes a valve mechanism, a trip mechanism, and a trip circuit. The trip mechanism includes a rotational spring that urges closing of the valve mechanism. A trip latch is adapted to prevent closing of the valve mechanism except when withdrawn from the valve mechanism by a solenoid that is electrically connected to the trip circuit. The trip circuit includes at least one trip sensor input and a power source, such that when the trip circuit detects a fault condition on any of the trip sensors, the trip circuit connects power to the solenoid to withdraw the solenoid to close the valve mechanism. A rest knob may then be rotated to reset the valve mechanism into a valve-open position.
