Causes of Breakage and Function Failure in Flushometers

17 August 2018

Flushometers are now very commonly used in the restrooms of all types of commercial businesses. While these are durable flush delivery systems that regulate water effectively, there are times when these breakdown and do not function properly as they should. When this happens, troubleshooting and minor repairs are often the prescribe remedy.

Basic flushometers consist of a pipe that extends out from the rear of a toilet, and that have a handle that is easily accessible from the side that is used to flush. When they do not function properly, and minor repairs are unsuccessful, then correcting the problem requires the help of a licensed plumber.

Causes of Flushometer Function Failure

When flushometers do not function properly, it can be difficult to determine the cause of the breakage. However, there are common causes of flushometer problems, knowing these can help with attempting to troubleshoot a solution before having to call in a plumber.

Common causes of flushometer function failure:

Strange noise during flushing – if there is a loud chattering or rumbling noise when flushing, the cause could be a damaged relief valve or diaphragm assembly. You can inspect if there is any physical damage by removing the flushometer cover and examining the relief valve and diaphragm assembly, and then replacing these if needed.

Continuous or long flush – when there is a long flush, or water flow is continuous, the problem is often caused by a faulty diaphragm assembly, or the filter rings are damaged and need to be replaced.

Toilet does not flush – often times when a flushometer does not flush it is because the handle assembly is broken. A broken flushometer handle will prevent water from flowing as it should, to fix the problem will require removing and replacing the handle assembly.

Incomplete short flush – it is frustrating when a flushometer doesn’t function as it should, such as when toilets have incomplete short flushes, it causes people to hold down the flushometer handle to complete the flush. Like most common flushometer problems, either a damaged diaphragm assembly or faulty handle assembly is usually the culprit. Simply replacing these can fix the problem.

Although flushometers are hardy plumbing mechanisms that can save up to 40% water use over traditional toilets, they can become worn with use and need to be serviced regularly to maintain their functionality. While there are guides online that show how to fix flushometer problems, it is highly advised to hire professional plumbers instead.
