Understanding and Troubleshooting the Sloan FlushMate's Loud Noise Issue
The Sloan FlushMate is a popular, water-saving flush valve that's known for its reliability and efficiency. However, like any mechanical device, it can sometimes develop issues, one of which is making loud noises. If your Sloan FlushMate is suddenly making a loud noise, don't worry - you're not alone, and there are several possible solutions to this problem.
Why is My Sloan FlushMate Making Loud Noises?
Several factors can cause your Sloan FlushMate to make loud noises. Here are some of the most common reasons:
- Air in the Lines: Air pockets in the water supply lines can cause the FlushMate to make a loud hissing or gurgling noise.
- Worn Out Internal Parts: Over time, the internal parts of the FlushMate can wear out, causing the valve to make loud noises when it opens or closes.
- Incorrect Installation: If the FlushMate was not installed correctly, it can cause excessive noise and other issues.
- Water Pressure Issues: Both high and low water pressure can cause the FlushMate to make loud noises.
Diagnosing the Issue: A Step-by-Step Guide
Before you can fix the issue, you need to diagnose the problem. Here's a step-by-step guide to help you determine the cause of the loud noise:

- Check the water pressure. Use a water pressure gauge to ensure the pressure is within the recommended range (40-80 psi). If the pressure is too high or too low, adjust it accordingly.
- Listen for any hissing or gurgling noises. If you hear these sounds, it's likely that there's air in the lines. You can bleed the air from the system to fix this issue.
- Inspect the FlushMate for any signs of wear and tear. If you notice any damaged or worn-out parts, they may need to be replaced.
- Check the installation. Ensure that the FlushMate was installed correctly. If not, you may need to reinstall it.
Fixing the Issue: Simple Solutions
Once you've diagnosed the issue, you can move on to fixing it. Here are some simple solutions to common FlushMate noise problems:
| Problem | Solution |
|---|---|
| Air in the Lines | Bleed the air from the system by opening the faucet on the highest fixture in your home and letting the water run until the air is gone. |
| Worn Out Internal Parts | Replace the worn-out parts with new ones. You can find replacement parts at most hardware stores or online. |
| Incorrect Installation | Reinstall the FlushMate according to the manufacturer's instructions. If you're unsure, consider hiring a professional plumber. |
| Water Pressure Issues | Adjust the water pressure to the recommended range (40-80 psi). If you're unsure how to do this, consult a professional plumber. |

If you've tried the solutions above and the noise persists, or if you're unsure about any part of the diagnosis or repair process, don't hesitate to call a professional.
In conclusion, a loud noise from your Sloan FlushMate can be a nuisance, but it's often a simple issue to fix.
