Safety First
Before embarking on any plumbing work, remember to turn off the water supply to your toilet. Locate the water shut-off valve behind the toilet and turn it clockwise to close it. Flush the toilet to drain the remaining water in the tank.
Step 1: Remove the Old Fill Valve
- Using an adjustable wrench, loosen the water supply line nut connecting the fill valve to the water supply.
- Hold the fill valve with one hand and use pliers to gently unhook the overflow tube from the fill valve.
- Lift the fill valve straight up to detach it from the tank.
Step 2: Install the New Fill Valve
- Align the new fill valve with the hole in the bottom of the tank.
- Push down on the fill valve to seat it securely in the hole.
- Hand-tighten the locknut on the underside of the tank to secure the fill valve.
Step 3: Connect the Water Supply Line
- Connect the water supply line to the fill valve by hand-tightening the nut.
- Use an adjustable wrench to gently tighten the nut further, ensuring a secure connection.
Step 4: Attach the Overflow Tube
- Reattach the overflow tube to the new fill valve by inserting the end of the tube into the designated hole on the fill valve.
- Secure the overflow tube with a small clamp or zip tie.
Step 5: Adjust the Fill Level
- Turn on the water supply to the toilet.
- Flush the toilet to fill the tank.
- Adjust the fill level by turning the adjustment screw on the fill valve. Turn clockwise to lower the fill level and counterclockwise to raise it.
- The ideal fill level is about 1 inch below the top of the overflow tube.
Step 6: Check for Leaks

- Tighten any loose connections as needed.
Step 7: Reinstall the Toilet Lid and Seat
- Replace the toilet lid and seat.
- Turn on the water supply to the toilet and flush it to test the new fill valve.

- Leaking fill valve: Ensure that the fill valve is seated properly and the locknut is tightened securely. Check for any cracks or damage to the fill valve.
- Toilet not filling: Verify that the water supply is turned on and the water supply line is connected properly. Adjust the fill level screw to increase the water flow.
