Abstract: A flush valve leakage prevention and detection device includes a hood for being assembled over a water inlet valve assembly of a toilet tank, a latch for being mounted by the hood for rotation from a locked position wherein a locking arm of the latch holds a float lever of the water inlet valve assembly in a raised position corresponding to a closed position for the water inlet valve assembly and an unlocked position wherein the locking arm is disengaged from the float lever to allow the float lever to move to a lowered position corresponding to an open position for the water inlet valve assembly in response to flushing of the toilet tank and a stop for preventing over rotation of the latch to the unlocked position to permit the latch to automatically return to the locked position upon filling of the toilet tank with water by the water inlet valve assembly.
Abstract: A flush valve leakage prevention and detection device includes a latch for supporting a float lever of a float controlled water inlet valve assembly of a toilet tank in a raised, latched position corresponding to a closed position for the water inlet valve assembly, with a control arm on the latch being engaged by a flush lever of the toilet tank. A support pivotally mounts the latch within the toilet tank, and the latch is rotationally biased relative to the pivot such that the control arm is urged in supporting engagement upon the flush lever and the latch is positioned to hold the float lever in the raised, latched position.
