Do you have the tools needed to install your new flush valve? View our Flushometer Tool Guide and discover which tools you need.


The particular sensor side mount operated flush valve featured here is capable of being installed in either a left- or right-handed handle position and, since the entire unit comes with all major components already in place, installation is quick and simple. It's a one gallon-per-flush diaphragm-type Flushometer, with a synthetic rubber called PERMEX® used to alleviate deterioration from chlorine in the water. The sensor operated single flush valve is powered by a set of four C-type batteries that reside beneath a chrome-plated cover. A flashing LED warns of low power, but the TMO button (true mechanical override) allows for flushing even when the batteries are dead.
