Safety Precautions

Before starting any repairs, it’s crucial to take safety precautions:

Step-by-Step Instructions:

• Inspect the fill valve seat where the old fill valve was attached.
• If there is any debris or mineral buildup, use a rag or brush to clean it thoroughly.

3. Install the New Fill Valve

• Wrap plumber’s tape around the threads of the new fill valve.
• Insert the fill valve into the fill valve seat and tighten the locknut using an adjustable wrench.

4. Adjust the Water Level

• Turn on the water supply and let the tank fill.
• Adjust the water level by turning the adjustment screw on the fill valve.
• The water level should be approximately 1 inch below the top of the overflow tube.

5. Check for Leaks

• Once the water level is adjusted, check for any leaks around the fill valve.
• If there are any leaks, tighten the locknut or replace the fill valve washer.

6. Reinstall the Toilet Tank

• Carefully lift the toilet tank and align it with the toilet bowl.
• Press down on the tank to secure it in place.

7. Turn on the Water Supply

• Turn on the water supply to the toilet and flush it to test the fill valve.

Troubleshooting Tips

• If the toilet is still leaking after replacing the fill valve, check the flapper valve for leaks.
