Abstract:
1. An auxiliary actuator for a toilet fill valve of the type having a fill valve float mechanism that lifts an arm in response to a rising water level in a toilet tank, the arm closing the toilet fill valve when lifted by the fill valve float mechanism, the auxiliary actuator comprising: a plunger slidably and vertically oriented under the arm of the toilet fill valve to lift the arm sufficiently to close the toilet fill valve when the plunger is in a raised position, a biasing means urging the plunger into the raised position; a solenoid mechanism normally de-energized and adapted to engage a latching mechanism of the plunger when the plunger is in a lowered position, the solenoid mechanism when energized disengaging from the latching mechanism to allow the plunger to be urged into its raised position by the biasing means; and an electronic sensing circuit including at least one sensor and a power source, the electronic sensing circuit 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.
