Abstract: A flush valve installation tool and associated method is used to install and uninstall chrome flush valves. The installation tool is capable of installing and uninstalling nuts of a variety of sizes without causing damage to the surfaces of the nuts. The flush valve installation tool has opposing first and second members coupled together by a pin or bolt. The first and second members each have two or more smooth jaw faces configured to engage 4 or 5 surfaces of a nut to be installed or uninstalled. The flush valve installation tool can be adjusted to select the distance between opposing jaw faces to accommodate different sized nuts.
