Have you ever experienced the frustration of a constantly running toilet? Not only is it irritating to listen to the constant flow of water, but it can also waste a significant amount of water, leading to increased water bills. One of the leading brands of toilets, Kohler, is no exception to this issue. However, there are several reasons why your Kohler toilet may be running and solutions to fix the problem.
In this article, we will explore the possible reasons why your Kohler toilet may be running and provide solutions to help resolve the issue. From simple fixes such as adjusting the flapper to more complex problems like a faulty fill valve, we will take a closer look at what could be causing your Kohler toilet to run and how to fix it. With our tips, you can save money on your water bill and enjoy a fully functioning Kohler toilet.
Broken or Worn Flapper
One of the common reasons why a Kohler toilet may continue to run even after flushing is a broken or worn flapper. The flapper is a rubber seal that forms a seal between the water tank and the toilet bowl. It lifts up when the toilet is flushed, allowing water to flow into the bowl, and then closes again to ensure that water doesn’t continue to flow from the tank.
If the flapper is damaged or has worn out, it may not seal completely, causing water to continue flowing from the tank into the bowl. This can eventually lead to a continuous flow of water that wastes a lot of water and can increase your water bill. However, the good news is that replacing a damaged or worn flapper is relatively simple and inexpensive. All you need to do is turn off the water supply line to the toilet, remove the old flapper from the hinge pins, and then install a new flapper in its place.
Faulty Fill Valve
A faulty fill valve is one of the most common reasons why Kohler toilets keep running. The fill valve is responsible for regulating the amount of water that enters the tank after each flush. If it isn’t functioning properly, the water level in the tank might not reach the right amount, causing the toilet to continue running around the clock.
The good news is that fixing a faulty fill valve is typically an easy and inexpensive job. Identifying the source of the problem takes some skill, but it can often be solved by simply replacing the valve. If you’re unsure about the status of your fill valve, you can easily check it by listening to the toilet after each flush. If the water doesn’t shut off correctly, you might have a faulty fill valve that needs replacing.

Mineral Build-Up in the Tank
If you notice that your Kohler toilet keeps running, mineral build-up might be the cause. Hard water is common in many areas, and the minerals in the water can cause lime scale to form in your toilet tank. This can prevent the flapper from closing properly, leading to a constant flow of water into the toilet bowl.
To fix this issue, you need to clean the tank thoroughly. Turn off the water supply to the toilet and flush the toilet to drain the tank completely. Next, pour some vinegar into the tank and let it sit for a few hours. Scrub the inside of the tank with a brush, paying close attention to the areas with visible mineral deposits. Finally, turn the water supply back on and let the tank refill. Once the tank is full, flush the toilet to make sure the flapper closes properly and the toilet stops running.
Malfunctioning Flush Valve
The flush valve of a Kohler toilet is responsible for releasing water from the tank into the bowl to flush out waste. If this part is malfunctioning, it can cause the toilet to continuously run. One of the most common reasons for this problem is a worn-out or damaged flush valve flapper. When the flapper is damaged, it can no longer provide a good seal, allowing water to leak from the tank to the bowl. This constant water flow can trigger the fill valve to keep filling the tank, making the toilet run non-stop.
To fix this issue, first, inspect the flapper to ensure that it is not torn or warped. If it is damaged, replace it immediately with a new Kohler-approved one. Another reason the flush valve may malfunction is if the chain that connects the flapper to the flush handle is too long, causing the flapper to stay open. Adjusting the chain so that it gives the flapper some slack but still closes it tightly can solve the problem. If these solutions don’t work, it may be necessary to replace the entire flush valve assembly to stop the toilet from running.

Improperly Installed Flapper or Fill Valve
If you’ve recently had your Kohler toilet repaired or replaced any parts, it’s possible that an improperly installed flapper or fill valve could be the cause of your running toilet. When installed incorrectly, the flapper or fill valve won’t form a tight seal, causing water to continuously run and waste water.
To fix this issue, turn off the water supply to your toilet and remove the tank lid. Check the flapper to ensure it’s connected securely to the chain and that it’s not worn or damaged. If the flapper is not the issue, check the fill valve’s placement to ensure it’s fitted correctly. Tighten any loose bolts or connections and replace any worn parts to ensure your toilet operates properly. If you’re not comfortable repairing the issue yourself, consider hiring a plumber to avoid further damage to your toilet.
Damaged Float or Float Arm
A damaged float or float arm is another common cause of a Kohler toilet that keeps running. The float is a buoyant device in the toilet tank that signals the fill valve to stop the water flow once the tank reaches the desired level. The float arm is the rod that connects the float to the fill valve.
If the float or float arm is damaged, the signal may not work properly, and the water will continue to run. A damaged float or float arm can be caused by wear and tear over time or by accidental damage during cleaning or maintenance. Carefully inspect both the float and float arm for any signs of damage or misalignment, and replace if necessary.
Replacing a damaged float or float arm is a relatively simple fix. You can purchase a replacement kit from a hardware store or plumbing supply store. Follow the manufacturer’s instructions to ensure proper installation. If you are unsure about installing a new float or float arm, consider contacting a professional plumber to do the job for you.

Low Water Pressure or Inadequate Water Supply
If you’re experiencing low water pressure or inadequate water supply in your Kohler toilet, it’s likely that it won’t flush correctly, leading to frequent running. Low water pressure can be caused by a fault in your plumbing or a problem with your water supply. To check if this is the case, try flushing other toilets in your home to see if they’re also experiencing water pressure issues.
If the low water pressure is isolated to your Kohler toilet, it could be due to a clogged inlet valve screen. The inlet valve screen is responsible for regulating the flow of water into your toilet tank, so if it’s blocked, water pressure will be reduced. To fix this, turn off the water supply to your toilet and remove the inlet valve cap. Clean the valve and the screen with a brush or a cloth. Additionally, if your home has old plumbing, inadequate water pressure could be caused by outdated pipes or fixtures, and you may need to replace them to improve your water pressure and prevent your Kohler toilet from running.
Final Words
In conclusion, a Kohler toilet that keeps running can be caused by various factors, including a fault in the flapper valve, a problem with the fill valve, or an issue with the water supply system. Conducting a thorough inspection of these components and repairing or replacing any faulty part can help to fix the problem.
Regular maintenance of your Kohler toilet is also crucial to prevent issues like running water. Simple tasks like cleaning the toilet bowl, adjusting the water level, and replacing worn-out parts can help keep your Kohler toilet running smoothly for years to come. Therefore, homeowners should not ignore any signs of a running toilet and should take immediate action to address the problem to avoid costly water bills and repairs.
