I have a men's urinal that is running non - stop. Where do I look to find the problem? Would it be a simple replacement of a gasket or a valve? How do I know which to do?

HelloCustomer

Welcome to Just Answer.

Sorry to hear about your problem.

 

When the water is not shutting off in the urinal, you will need to check the following:

 

The relief valve may not be seating properly or the by-pass orifice is clogged because of foreign material, or the by-pass orifice is closed by an invisible gelatinous film from over-treated water. If this is the case, you will need to disassemble the working parts and wash thoroughly. The size of the orifice in the by-pass is of utmost importance for proper metering of water into the upper chamber of the flushometer. DO NOT enlarge or damage this orifice. Replace inside kit if cleaning does not correct the problem.

 

The line pressure may have dropped and is not sufficient enough to force the relief valve to seat. If this is the case, you will need to shut off all control stops until pressure has been restored, then open them again.

 

An A-19-AC (white) closet relief valve may have accidentally been used in a 1 or 1-1/2 gpf urinal. If so, replace with A-19-AU (black) relief valve.

Inside cover may be cracked or damaged. If so, replace the inside cover (A-71).
