Flush valve leakage prevention and detection device

摘要

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. That latch includes a control arm disposed in resting engagement upon a flush lever of the toilet tank to rotate the locking arm to the unlocked position in response to movement of the flush lever due to flushing. The hood includes a plurality of gripping arms allowing the hood to be assembled to the water inlet valve assembly with a snap fit and opposing side walls. The locking arm and stop extend between the hood and side walls with the stop being spaced from the locking arm in the direction of rotation of the latch to the unlocked position.
