Materials You’ll Need
- New fill valve for Kohler one-piece toilet
- Adjustable wrench
- Screwdriver
- Rags or towels
Step 1: Turn Off the Water Supply
Locate the water supply valve behind the toilet. Turn the valve clockwise to shut off the water supply.
Step 2: Flush the Toilet
Flush the toilet to drain the tank. Use a rag or towel to absorb any remaining water.
Step 3: Disconnect the Water Supply Line
Use an adjustable wrench to disconnect the water supply line from the fill valve. Place a rag under the connection to catch any water that may leak.
Step 4: Remove the Old Fill Valve
Use a screwdriver to remove the screws that hold the fill valve in place. Gently pull the old fill valve straight up to remove it from the toilet tank.
Step 5: Install the New Fill Valve
Insert the new fill valve into the hole in the toilet tank. Align the valve with the holes and secure it with the screws.
Step 6: Reconnect the Water Supply Line
Hand-tighten the water supply line to the new fill valve. Use the adjustable wrench to tighten the connection further, but avoid overtightening.
Step 7: Adjust the Fill Valve Height
The fill valve height determines the water level in the tank. Adjust the height of the fill valve by turning the adjustment screw on the valve. Turn the screw clockwise to raise the water level and counterclockwise to lower it.
Step 8: Test the Fill Valve
Turn on the water supply valve and flush the toilet. Check for any leaks around the fill valve. If there are leaks, tighten the connection or adjust the fill valve height as needed.
Troubleshooting Tips
- If the toilet continues to run after the fill valve is replaced, check for leaks in the flapper valve or tank gasket.
- If the water level in the tank is too high or too low, adjust the fill valve height as described in Step 7.
- If the new fill valve is noisy, check for loose connections or debris in the valve.
