3. Fixing the Problem

If your Kohler toilet is running, there are a few possible causes and solutions. Here are the most common problems and how to fix them:

  • Flapper valve: The flapper valve is a rubber disk that sits in the bottom of the toilet tank and seals the opening to the bowl. When you flush the toilet, the flapper valve opens, allowing water to flow from the tank into the bowl. If the flapper valve is not sealing properly, water will continue to flow into the bowl, causing the toilet to run. To fix this problem, you will need to replace the flapper valve.
  • Flush valve: The flush valve is a metal or plastic valve that sits in the bottom of the toilet tank and controls the flow of water into the bowl. When you flush the toilet, the flush valve opens, allowing water to flow from the tank into the bowl. If the flush valve is not working properly, it may not be opening or closing all the way, which can cause the toilet to run. To fix this problem, you will need to replace the flush valve.
  • Fill valve: The fill valve is a valve that sits in the back of the toilet tank and controls the flow of water into the tank. When the tank is empty, the fill valve opens, allowing water to flow into the tank. When the tank is full, the fill valve closes, preventing any more water from flowing into the tank. If the fill valve is not working properly, it may not be opening or closing all the way, which can cause the toilet to run. To fix this problem, you will need to replace the fill valve.
  • Water supply line: The water supply line is the pipe that connects the water supply to the toilet. If the water supply line is leaking, it can cause the toilet to run. To fix this problem, you will need to replace the water supply line.
