How to Replace a Kohler Toilet Flapper

Your toilet flapper is a small but important part of your toilet. It’s responsible for keeping the water in the bowl from draining out when you’re not using the toilet. Over time, the flapper can wear out and start to leak. If you notice that your toilet is running constantly, or if the water level in the bowl is too low, it’s likely that the flapper needs to be replaced.

Replacing a Kohler toilet flapper is a relatively simple task that can be completed in just a few minutes. In this article, we’ll walk you through the steps of how to replace a Kohler toilet flapper, so you can get your toilet back to working properly in no time.

What You’ll Need

• New Kohler toilet flapper
• Adjustable wrench
• Pliers
• Bucket
• Paper towels

Step 1: Turn Off the Water Supply

The first step is to turn off the water supply to the toilet. This will prevent any water from spilling out when you remove the old flapper. To do this, locate the water supply valve located under the sink or behind the toilet. Turn the valve clockwise until it is completely closed.

Step 2: Remove the Old Flapper

Once the water supply is turned off, you can begin to remove the old flapper. There are two tabs on the sides of the flapper that you need to pry up with a flathead screwdriver. Once the tabs are pried up, you can lift the flapper off of the valve stem.

Step 3: Clean the Valve Stem

Before you install the new flapper, you need to clean the valve stem. This will help to ensure that the new flapper seals properly. To do this, use a paper towel to wipe off any dirt or debris from the valve stem.

Step 4: Install the New Flapper

Now it’s time to install the new flapper. Take the new flapper and align it with the valve stem. Make sure that the tabs on the flapper are facing up. Press down on the flapper until it snaps into place.

Step 5: Turn on the Water Supply

Now that the new flapper is installed, you can turn on the water supply. Be sure to check for leaks around the flapper. If you see any leaks, tighten the flapper until the leaks stop.

Step 6: Flush the Toilet

Finally, flush the toilet to make sure that the new flapper is working properly. The water should fill the bowl and then drain out slowly. If the water drains out too quickly, you may need to adjust the flapper.
