Picture this: You’re in your bathroom, enjoying some peace and quiet, when suddenly you hear it—the unmistakable sound of a running toilet. That little leak might seem harmless, but it can waste gallons of water and inflate your utility bills before you even realize it!
If your Sloan flush valve is leaking, don’t panic. This guide will walk you through how to fix it step by step.
Common Causes of a Leaking Sloan Flush Valve
Before diving into repairs, let’s identify why your Sloan flush valve is leaking. The most common causes include:
- Worn-out Diaphragm Kit – Over time, the rubber diaphragm inside the valve deteriorates, causing leaks.
- Damaged or Dirty Vacuum Breaker – If debris or wear affects the vacuum breaker, leaks can occur.
- Faulty Handle Assembly – A worn handle can cause the valve to run continuously.
- Incorrect Flush Volume Settings – Adjusting the flush volume incorrectly can lead to persistent water flow.
Understanding the cause of the leak is the first step toward a successful repair!
Step-by-Step Guide to Fixing a Leaking Sloan Flush Valve
1. Gather Your Tools and Supplies
Before starting, make sure you have the following tools:
- Adjustable wrench
- Flathead screwdriver
- Replacement diaphragm kit (specific to your Sloan model)
- Replacement vacuum breaker if needed
- Cleaning cloth or rag
2. Shut Off the Water Supply
- Locate the shutoff valve on the water line leading to the flushometer.
- Turn it clockwise to stop the water flow.
- Flush the toilet to empty the remaining water from the system.
3. Inspect and Replace the Diaphragm Kit
- Remove the top cover of the Sloan flush valve using a wrench.
- Take out the old diaphragm and inspect it for wear or damage.
- If it’s torn or stiff, replace it with a new Sloan flush valve diaphragm kit.
4. Check and Clean the Vacuum Breaker
- Remove the flushometer’s vacuum breaker.
- If there’s mineral buildup, clean it with vinegar and a brush.
- If the breaker is cracked or too worn, replace it.
5. Inspect and Adjust the Handle Assembly
- If the handle sticks or doesn’t return to its original position, it might be worn.
- Replace the handle assembly if necessary.
6. Reassemble and Test the Valve
- Reattach the top cover securely.
- Turn the water supply back on slowly.
- Flush and observe for leaks.
- Adjust the flush volume if needed.
If the leak persists after these steps, consider contacting a professional plumber in Easton for further troubleshooting.
