- New fill valve
- Adjustable wrench

Step-by-Step Instructions
1. Turn Off the Water Supply
The first step is to turn off the water supply to your toilet. Locate the water supply valve behind the toilet and turn it clockwise to close it.
2. Flush the Toilet
Flush the toilet to empty the tank. This will make it easier to work on the fill valve.
3. Disconnect the Water Supply Line
Use the adjustable wrench to disconnect the water supply line from the fill valve. Be careful not to overtighten the wrench.
4. Remove the Old Fill Valve
Use the screwdriver to remove the screws that hold the fill valve in place. Once the screws are removed, the fill valve can be lifted out of the tank.
5. Install the New Fill Valve
Place the new fill valve into the tank and align it with the holes. Secure the fill valve with the screws.
6. Connect the Water Supply Line
Connect the water supply line to the fill valve. Tighten the connection with the adjustable wrench.
7. Adjust the Fill Height
The fill height is the level at which the water fills in the tank. To adjust the fill height, turn the adjustment screw on the top of the fill valve clockwise to raise the water level or counterclockwise to lower the water level.
8. Test the Fill Valve
Turn on the water supply and flush the toilet. Observe the fill valve to make sure it’s working properly. The water should fill the tank to the correct level and stop automatically.
Troubleshooting
If you’re having trouble replacing the fill valve, here are a few troubleshooting tips:
- The water is still running after the tank is full. The fill valve may be defective. Replace the fill valve with a new one.
- The water level in the tank is too low. The fill height may be set too low. Adjust the fill height screw to raise the water level.
- The water level in the tank is too high. The fill height may be set too high. Adjust the fill height screw to lower the water level.
