Abstract
A flush valve operating arrangement, having a pair of tubes between a flush valve actuator assembly and a remotely controlled unit for operating a flush valve; a third tube under supply line pressure is connected between the flush valve and the remotely controlled unit, which is responsive to supply line pressure from the third tube, and a control, coupled with the pair of tubes and with a fixture connected with the flush valve, responsive to water level in the fixture for prevention of actuation of the flush valve actuator assembly by the remote unit to thereby prevent overflow of the fixture and flooding of a surrounding area.
A water level sensor is associated with the fixture, and includes a piston-housing assembly having an inlet and an outlet associated with the housing, a plunger associated with the water level sensor device either to isolate the inlet from the outlet or to place them into communication depending on the level of water in the fixture, and a bleed inlet line connected from one pair of the tubes to the inlet, and an outlet line connected from the water level sensor to a drain for diverting water in the one tube to the drain when the sensor activates the plunger to place the inlet and the outlet into communication and the remotely controlled unit is operated to place the pair of tubes into communication with the third tube.
