How to replace fill valve and flush valve on Kohler toilet

Replace fill valve and flush valve

It might be time to consider replacing the fill valve or flush valve if you’re experiencing issues with your Kohler toilet such as a constantly running tank or weak flush. The fill valve valve and flush valve control the flow of water into and out of the toilet tank.  These valves can wear out or become clogged with hard water scale over time. Rather than hiring a plumber to fix the problem, consider tackling this project on your own! Not only will you save money, but you’ll also gain a sense of accomplishment and learn new skills.


Step-by-step instructions

Here’s the basic step by step instructions of how to replace a fill valve and flush valve on a Kohler toilet:

  1. Shut off the water supply: First, locate the water supply valve for your toilet and turn it off. This valve is usually located behind the toilet or on the wall behind the toilet.
  2. Drain the tank: Flush the toilet to drain as much water out of the tank as possible. Then, use a sponge to remove any remaining water and a towel to dry the inside of the tank.
  3. Remove the old valve: Depending on the type of valve you’re replacing, you may need to use a wrench or pliers to loosen the mounting bolts and remove the old valve. Be gentle and take your time to avoid damaging the tank or any other parts.
  4. Install the new valve: Follow the manufacturer’s instructions to install the new valve. This usually involves fitting the valve into place and tightening the mounting bolts. Make sure the valve is properly aligned and seated.
  5. Attach the supply line: If you’re replacing the fill valve, attach the supply line to the valve using the compression fitting provided. If you’re replacing the flush valve, attach the flush handle to the valve using the mounting hardware provided.
  6. Turn on the water supply: Once you’ve installed the new valve, turn the water supply valve back on and test the toilet to make sure it’s flushing properly. If you notice any leaks or other problems, make any necessary adjustments.

Don’t be intimidated by the thought of replacing a fill valve or flush valve on your Kohler toilet. With a little bit of know-how and some basic tools, you can tackle this project with confidence and achieve great results. Good luck!
