How to Fix a Urinal that Won’t Flush

The restrooms are an important part of your commercial space. Not having a properly functioning restroom can affect both your employees’ and your customers’ experience. So if you have a urinal that won’t flush correctly or at all, you need to get it up and running again, fast.

A urinal that won’t flush correctly or a urinal that won’t flush at all is a common problem and more often than not it is caused by an issue with the flush valve.

3 Ways To Fix a Urinal that Won’t Flush Correctly or at All

Read on for three ways your urinal can malfunction and what you can do to troubleshoot the problem.

1. The Urinal Won’t Flush at All

The problem: The flush valve doesn’t function at all

If the flush valve isn’t functioning at all, your urinal can’t flush. This can occur when the control stop or the main valve is closed, if the handle assembly is worn, or if the relief valve is worn.

The solution: Reopen the valve or replace worn parts

Depending on which issue above is afflicting your flush valve, you can try to reopen the control stop or main valve, install a handle repair kit, or replace the valve if it’s worn out.

2. The Urinal Flush Is Too Short

The problem: A short flush cycle occurs every time the urinal is flushed

When a urinal is flushed, the flush cycle should be long enough that the bowl can refill with a specific amount of water. If the flush cycle is too short, a series of problems can occur.

The solution: It depends…

If the length of the urinal flush is too short, there are a handful of potential underlying causes. How you address the problem will depend on what is causing the short flush.

One of the most likely culprits is that the diaphragm assembly and guide assembly aren’t hand tight. This is easily fixed by tightening them.

Another potential culprit is that the by-pass orifice is enlarged due to corrosion or damage. In this case, the by-pass orifice will need to be replaced or repaired.

3. The Urinal Flush Is Too Long

The problem: A long flush cycle occurs every time the urinal is flushed

When a urinal is flushed, the flush cycle should be just long enough that the bowl can refill with a specific amount of water. If the flush cycle is too long, a series of problems can occur.

The solution:

If the length of the urinal flush is too long, there are a handful of potential underlying causes. How you address the problem will depend on what is causing the short flush.

One of the most likely culprits is that the relief valve is not seated properly. We recommend disassembling the valve to check that everything is positioned correctly.

In some cases, the bypass orifice can become clogged. This can impede water flow and throw off the urinal’s cycle, resulting in a longer cycle overall. If you suspect this is the case, disassemble the working parts and clean everything thoroughly.
