Quick Fix for a Dripping Toilet: DIY Flush Valve Washer Replacement Guide

Are you tired of a constantly running toilet? A faulty flush valve washer could be the culprit. Replacing it is a relatively simple plumbing task that can save you money and frustration. Follow this comprehensive guide to learn how to replace flush valve washer in no time.

Why Replace a Flush Valve Washer?

The flush valve washer is a small rubber or plastic disk that seals the flush valve against the tank. Over time, it can wear out or become damaged, causing the toilet to run continuously. This not only wastes water but can also increase your water bill.

Tools and Materials You’ll Need:

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

Step-by-Step Instructions:

1. Turn Off the Water Supply:

Locate the water supply valve behind the toilet and turn it off clockwise. Flush the toilet to empty the tank.

2. Remove the Toilet Lid:

Lift the toilet lid off the tank.

3. Disconnect the Water Supply Line:

Use an adjustable wrench or pliers to loosen the nut connecting the water supply line to the fill valve. Disconnect the line and place it in a safe place.

4. Flush the Toilet:

Flush the toilet to drain any remaining water from the tank.

5. Remove the Flush Valve Cap:

Locate the flush valve cap at the bottom of the tank. It usually has a small chain or handle attached to it. Turn the cap counterclockwise by hand or use a screwdriver to loosen it.

6. Remove the Old Washer:

Once the cap is removed, you will see the old washer. Gently pry it out using your fingers or a small tool.

7. Install the New Washer:

Take the new washer and place it over the flush valve seat. Make sure it is seated properly and facing the correct direction.

8. Replace the Flush Valve Cap:

Replace the flush valve cap by turning it clockwise until it is snug.

9. Reconnect the Water Supply Line:

Reattach the water supply line to the fill valve and tighten the nut using an adjustable wrench or pliers.

10. Turn On the Water Supply:

Turn the water supply valve back on counterclockwise.

11. Check for Leaks:

Flush the toilet and check for any leaks around the flush valve. If you see any leaks, tighten the flush valve cap further or replace the washer again.

Troubleshooting Tips:

• If the toilet still runs after replacing the washer, check the fill valve for leaks.
• If the flush valve cap is difficult to remove, apply a penetrating lubricant to the threads.
• If you are not comfortable replacing the washer yourself, call a licensed plumber for assistance.

Final Thoughts:

Replacing a flush valve washer is a simple and cost-effective way to fix a running toilet. By following these step-by-step instructions, you can save money and keep your toilet functioning properly.
