How To Fix Kohler Toilet Fill Valve?

This guide will show you how to fix a Kohler toilet fill valve. The fill valve is responsible for filling the toilet tank with water. If the fill valve is not working properly, the toilet may not fill up all the way, or it may leak water.

To fix a Kohler toilet fill valve, you will need the following tools:

  • Adjustable wrench
  • Flathead screwdriver
  • Pliers
  • New fill valve

Step 1: Turn off the water supply to the toilet.

The first step is to turn off the water supply to the toilet. This will prevent any water from leaking out of the toilet tank while you are working on the fill valve.

To turn off the water supply, locate the water supply valve under the sink or behind the toilet. The valve will be a small, round, or rectangular-shaped valve. Turn the valve clockwise to turn off the water.

Step 2: Remove the old fill valve.

The next step is to remove the old fill valve. To do this, you will need to loosen the nuts that connect the fill valve to the water supply line and the toilet tank.

The nuts will be located on the bottom of the fill valve. Use the adjustable wrench to loosen the nuts. Be careful not to drop the nuts into the toilet tank.

Once the nuts are loose, you can pull the fill valve out of the tank.

Step 3: Install the new fill valve.

The next step is to install the new fill valve. To do this, you will need to align the new fill valve with the holes in the toilet tank.

Once the fill valve is aligned, you can insert the nuts into the holes and tighten them with the adjustable wrench. Be careful not to overtighten the nuts.

Step 4: Turn on the water supply to the toilet.

The final step is to turn on the water supply to the toilet. This will allow the toilet tank to fill up with water.

To turn on the water supply, turn the valve counterclockwise.

That’s it! You have now successfully fixed your Kohler toilet fill valve. If you have any questions, please consult a qualified plumber.
