Abstract
An auxiliary actuator for a toilet fill valve comprises a plunger oriented under an arm of the toilet fill valve to lift the arm to close the toilet fill valve when the plunger is in a raised position. A spring or hydraulic mechanism urges the plunger into the raised position. A solenoid mechanism is normally de-energized and engages a latching mechanism of the plunger when the plunger is in a lowered position. An electronic sensing circuit has at least one sensor and a power source. The electronic sensing circuit is electrically connected with the solenoid mechanism to energize the solenoid mechanism upon detection of a fault condition based on the input of the at least one sensor. Fault conditions may include a flush valve leak, a stuck-open flush valve, a plugged toilet, and a leaking fill valve.
