Symptoms of a Fill Valve Leak

Here are some telltale signs that your fill valve needs attention:

• Constant running water in the toilet bowl
• Water level in the tank is too high or too low
• Hissing or gurgling noises coming from the fill valve
• Water stains or mold around the base of the toilet

Tools and Materials You’ll Need

Before you start, gather these tools and materials:

• Adjustable wrench
• Plumber’s tape
• New fill valve
• Screwdriver (optional)

Step-by-Step Guide to Fixing a Toilet Fill Valve Leak

1. Turn Off Water Supply

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

2. Disconnect Water Supply Line

Using an adjustable wrench, disconnect the water supply line from the fill valve. Be careful not to overtighten or damage the line.

3. Remove Old Fill Valve

Unscrew the nuts or screws holding the old fill valve in place. Gently lift the valve out of the tank.

4. Install New Fill Valve

Wrap plumber’s tape around the threads of the new fill valve. Insert the valve into the tank and tighten the nuts or screws securely.

5. Reconnect Water Supply Line

Reattach the water supply line to the fill valve. Tighten the connection using an adjustable wrench.

6. Adjust Water Level

Adjust the water level in the tank by turning the adjustment screw on the top of the fill valve. The water level should be about 1 inch below the top of the overflow tube.

Turn the water supply valve back on counterclockwise. Check for any leaks around the fill valve. If there are no leaks, you’re all set!
