Tools and Materials You’ll Need

• Adjustable wrench or pliers
• New flush valve washer
• Screwdriver (optional)
• Rag or towel

Step-by-Step Instructions

1. Turn Off the Water Supply

Locate the water supply valve behind the toilet and turn it clockwise to shut off the water.

2. Flush the Toilet

Flush the toilet to drain the tank. Continue holding down the flush lever until all the water has drained.

3. Disconnect the Water Supply Line

Use an adjustable wrench or pliers to disconnect the water supply line from the fill valve.

4. Remove the Flush Valve Cap

Use a screwdriver or your hands to remove the flush valve cap. This is usually located on top of the flush valve assembly.

5. Remove the Flush Valve Seat

Once the flush valve cap is removed, you will see the flush valve seat. This is a rubber or plastic ring that seals against the flush valve washer. Use your fingers to gently pry the flush valve seat out of place.

6. Inspect the Flush Valve Washer

Inspect the old flush valve washer for any signs of wear or damage. If the washer is cracked, torn, or deformed, it needs to be replaced.

7. Install the New Flush Valve Washer

Place the new flush valve washer over the flush valve seat. Make sure that the washer is seated properly and is not twisted or folded.

8. Reinstall the Flush Valve Seat

Reinsert the flush valve seat into the flush valve assembly. Push it down until it is fully seated.

9. Reinstall the Flush Valve Cap

Screw the flush valve cap back onto the flush valve assembly. Hand-tighten the cap until it is snug.

10. Reconnect the Water Supply Line

Reconnect the water supply line to the fill valve. Use an adjustable wrench or pliers to tighten the connection.

11. Turn On the Water Supply

Turn the water supply valve counterclockwise to turn on the water.

12. Test the Flush Valve

Flush the toilet to test the flush valve. Make sure that there are no leaks and that the toilet flushes properly.

Troubleshooting Tips

• If the toilet still leaks after replacing the flush valve washer, the problem may be with the flush valve seat. Inspect the seat for any damage or wear and replace it if necessary.
• If the toilet flushes slowly, the problem may be with the water supply line. Check the line for any kinks or obstructions and clear them as necessary.
• If the toilet flushes continuously, the problem may be with the fill valve. Replace the fill valve if necessary.
