How to Stop A Commercial Toilet That Won't Stop Flushing

If the toilets in your Park Ridge, IL, building are equipped with flushometers, you know that they do a great job most of the time. Sometimes, however, a flushometer can get stuck in a cycle of endless flushes, which could lead to a toilet overflow or even a toilet flood. The best way to stop a toilet from flushing repeatedly depends on the type of flushometer.

Automatic Flushometer
To fix an automatic flushometer that won’t stop flushing, first shut the water off to the device. You can usually do this using a large flathead screwdriver. Next, press and hold the manual flush button.

If you hear a series of two clicks, then the problem is most likely with the diaphragm assembly. You will need to remove the top of the flushometer and clean any dirt or debris from the diaphragm. Check your manual for the exact steps for your flushometer model. If the flushing persists, you may need to replace the diaphragm assembly.

If you do not hear clicks, the issue may be with the solenoid. Follow the instructions in your flushometer’s manual to remove the top of the flushometer and locate the solenoid. Tighten all connections and check for any missing or improperly stacked bowl rings.

If the toilet continues to flush, try replacing the quad seal to avoid a toilet overflow.

Manual Flushometer

Shut off the water to the device as described above. Using a wrench, loosen and unscrew the cap on the top of the flushometer and remove the cap. Next, remove the flange cover to reveal the gasket. Remove the gasket and clean it thoroughly under warm water. Use a small pin or needle to ensure that the gasket’s weep hole is completely clear of any sediment. Return the gasket and reassemble the flushometer. If the flushing continues, you likely need a new gasket.

If your building has a toilet that won’t stop flushing, make sure you repair it right away. Otherwise, you could find yourself dealing with water damage restoration as a result of a toilet overflow.
