The diaphragm kit sits directly below the inside cover in the top of a flush valve. It regulates the pressure within a flush valve and when the flushometer handle is pulled, it controls the volume of the flush.

Generally speaking, a flushometer diaphragm will last around 4 years in a busy environment (about 250 thousand flushes!), however, this can be affected by water quality, especially sediment and other contaminants.

If your toilet or urinal flushometer no longer flushes when the handle is pulled, the relief valve (which is part of this kit) may be damaged or overworn. If the flush is too long, or does not shut off afterwords, the diaphragm may be damaged, clogged, or corroded. This drop-in kit is designed to quickly, and simply fix both of these issues. Just be sure to get the right one, based on your flushometer and how many gpf (gallons per flush) it is designed for.

A worn vacuum breaker (also included in this kit) can cause water to leak around the base of the downward tube where it attaches to the fixture, especially when the flush cycle ends. It is important to address this quickly as it can also be a sign that backflow is occuring which will potentially contaminate the water supply.

If water is leaking around the handle on your flushometer, or the fixture is no longer flushing when you pull the handle, the included handle kit can help resolve those issues as well.
