What To Know
- Use the adjustable wrench to loosen the nut that connects the fill valve to the water supply line.

- To adjust the height, turn the adjustment screw on the top of the fill valve clockwise to lower the water level or counterclockwise to raise it.
Replacing a faulty fill valve in your Kohler toilet is a relatively straightforward task that can save you both time and money. Whether you’re a seasoned DIYer or a plumbing novice, this comprehensive guide will empower you to tackle this project with confidence.
Tools and Materials You’ll Need
- Adjustable wrench
- Screwdriver
- Pliers
- New Kohler fill valve
- Plumber’s tape
- Rags or paper towels
Step 1: Gather Your Materials and Prepare the Area
Before you begin, gather all the necessary tools and materials. Shut off the water supply to the toilet by turning the valve located behind it. Flush the toilet to drain the tank. Place rags or paper towels around the base of the toilet to absorb any spills.
Step 2: Remove the Old Fill Valve
Use the adjustable wrench to loosen the nut that connects the fill valve to the water supply line. Disconnect the line and remove the old fill valve.
Step 3: Install the New Fill Valve
Apply plumber’s tape to the threads of the new fill valve. Insert the valve into the tank and hand-tighten the nut onto the water supply line. Use the adjustable wrench to snugly tighten the nut, but avoid overtightening.
Step 4: Connect the Water Supply Line
Reconnect the water supply line to the fill valve and tighten the nut securely. Turn on the water supply and check for leaks. If you notice any leaks, tighten the nut further.
Step 5: Adjust the Fill Valve Height
The fill valve should be adjusted so that the water level in the tank is about 1 inch below the top of the overflow tube. To adjust the height, turn the adjustment screw on the top of the fill valve clockwise to lower the water level or counterclockwise to raise it.
Step 6: Check for Leaks Again
Once the fill valve is adjusted, flush the toilet to fill the tank. Inspect all connections for leaks. If any leaks appear, tighten the nuts or fittings as needed.
Step 7: Reassemble the Toilet
Replace the toilet lid and seat. Turn on the water supply and check for leaks one final time. Your Kohler toilet is now ready to use!
Tips for Success
- If you encounter any stubborn bolts or nuts, use penetrating oil to help loosen them.
- Don’t overtighten any of the nuts or fittings, as this can damage the components.
- If you’re not comfortable replacing the fill valve yourself, don’t hesitate to call a licensed plumber for assistance.
