Abstract
A device and method for engaging the fill valve assembly in a water closet and maintaining the fill valve assembly in a closed condition regardless to the level of water in the flush tank of the water closet. The device includes two suspension elements that engage the walls of the flush tank on either side of the float lever portion of the fill valve assembly. A flexible element extends between the two suspension elements, wherein the flexible element passes under the float lever as extends from one suspension element to the other. As the flexible element is pulled taut, the flexible element abuts against the float lever and upwardly biases the float lever. The upward bias that is applied to the float lever causes the fill valve assembly to close. The upward bias also prevents the fill valve assembly from leaving its closed configuration regardless to the level of water in the flush tank.
