Is your Kohler toilet running intermittently? If so, you’re not alone. Thousands of homeowners have had this issue. In this article, we’ll show you how to fix it. So don’t worry – your toilet will be running smoothly again in no time.

There are 2 problems that can cause your toilet to run non-stop. Kohler toilets can suffer from leaks in the tank. This can be caused by several factors, but is mainly due to an improper set or damaged flapper/seal or broken fill valve.

How Does A Kohler Toilet Work?

Kohler toilets work by lifting an arm that pulls on a chain. The flapper valve is lifted, allowing water to flow into the toilet bowl, to flush away waste. When the arm is released, the flapper valve will drop back down and the fill valve will refill the tank.

Why Is My Kohler Toilet Running Intermittently?

If you are hearing an intermittent running sound from your toilet, there may be a leak. The water will run into the bowl even when it isn’t being flushed.

If your Kohler toilet is running intermittently, chances are there is a problem with the flapper seal or broken fill valve.

Diagnose The Cause

The first step is to figure out what is causing your Kohler toilet to run intermittently. There are a few things that could be the culprit.

To find the cause of your Kohler toilet’s problem, follow these 3 steps:

  1. Fill up with water and mark where it sits inside the tank.
  2. Turn off your water supply.
  3. Let the toilet sit unused for six hours or more.

The Water Level Remained The Same

If the water level in your tank is exactly where you left it, then the problem is most likely with the fill valve. The fill valve is responsible for bringing water into the tank.

There are two types of fill valves: ballcock-type and float cup-type. Either of these fill valve types could be stuck in the open position.

The Water Is At The Level Of The Flapper

If the water level has dropped to the level of the flapper, then there is most likely a problem with the flapper itself.

It might be warped and no longer seated properly, or it might be damaged and needs to be replaced.

The Water Is Completely Gone

If the water in your tank is completely gone, then there could be an issue with the fill valve.

The problem could be with the seal or the O-ring. If the seal or O-ring is damaged, it might not be sealing properly and water could be leaking into the fill valve.

  1. Turn off the water to your toilet. This is usually done by turning your water supply valve clockwise.

  5. Clean the area around the valve seat with a cloth.
  6. Install the new fill valve, making sure it’s seated correctly. Place the new fill valve so that the float is approx 1 inch above the top of water.

  8. Reconnect the supply line to the bottom of the fill valve.
  9. Turn on the water to your toilet and check for leaks.
