kohler cimarron toilet problems & troubleshooting

No matter how well-made a toilet is, there will be a point when there are issues that you need to fix. This article about Kohler Cimarron toilet problems & troubleshooting is made. You have to diagnose the issue first so you can apply the solution. By knowing the appropriate steps here, you may not need to hire a plumber.

The issues that you can encounter with your Cimarron toilet are on its flush, tank, and handle. You can’t just judge this toilet as lousy if it’s not flushing, or the flush is poor. The tank may not stop from refilling or the water may flow sporadically. Cimarron toilets are made to bring comfort and convenience. Before misjudging, know the causes of the problems as well as the steps for troubleshooting Kohler toilet.

Various Problems of Kohler Cimarron Toilet and Proper Troubleshooting


Here are the possible Kohler toilets problems and the proper repair instructions.

Issues with the Handle

1. Broken Handle

The metal handle is much better than the plastic one as the latter breaks easily. But they both easily accumulate dust, dirt, and lime build-ups. It usually occurs around the interior nut, handle threads, and interior tank mechanism. To remove the grime accumulation, wipe the nut and threads with vinegar.

Unfortunately, a handle that hangs vertically can no longer be fixed. It means replacement is essential. Just to be sure, check the connection of the lever and the chain as well as the nuts and thread. When there’s a stripped thread, replacing the handle is your final resort. You only need to buy new ones if the nuts are missing.

2. Loose Handle


When the handle is loose, you can blame it on a broken flush lever, or it can be unattached. There are various scenarios when fixing Kohler toilets. The flush lever or lift arm is a stick that is either made of plastic or metal with some holes. A chain that goes to the seal or flapper located at the tank’s bottom is inserted through one of the holes. You have no choice but to replace the handle.

3. Disconnected or Too Long Chain

The handle will be loose if the chain is disconnected and the result is a toilet that is not flushing. This issue is easy to fix by checking the inside of the tank. Make sure that the chain is attached to the hook lever and flapper which are all situated at the bottom part. Another situation is that the chain may be too long.

If this is the case, remove the chain and put the end in a higher hole. After adjustment, flush your toilet to check if you fixed it or not. When it still doesn’t work properly, continue finding the right length for your toilet to flush properly.

Issues with Flushing

1. No Flush

  1. The chain of the trip lever should be connected to the handle. Reconnect the chain if the Kohler toilet won’t flush.
  2. Adjust the chain link as mentioned above for the needed slack.
  3. You may also need to make the trip lever parallel to the tank’s top. In addition, the trip arm bracket should remain flat on the tank’s interior. You have to make sure that it’s in a vertical position when on the bottom of the tank.

2. Poor Flush

  1. There may be too much slackness in the chain. You’ll need to take out one or two links from it.
  2. See to it that the hose is properly connected to the canister’s top.
  3. Another reason that your Cimarron doesn’t flush completely is the waterline. There’s a designated line so make sure that the water in the tank reaches the mark.
  4. It’s also crucial to clean the holes under the rim of the elongated or round seat.
  5. Moreover, clear the trapway of any obstructions. You may use a plunger to finish it quickly.

3. Water Running Non-stop

  1. There are two ways of Kohler toilet troubleshooting this issue. You can replace the fill valve or just clean the fill valve seat. The latter is the best solution when nothing happens after lowering the tank’s water level.
  2. You can also try adjusting the flange and trip arm bracket, so these parts are parallel to the top of the tank.

4. Sporadic Water Flow

  1. The chain must be in the right slack, so the seal is not stuck with the flush valve seat.
  2. Adjust the water level when the water overflows into the toilet. Leakage can also give you a headache.
  3. This can happen when the seal is dirty and worn out. Clean it if it’s still applicable, but you may need to replace it. Another possibility is that the flush valve seat is misaligned or damaged, so replacement is a must.

5. Noisy Tank Refill

  1. When the tank becomes noisy during refills, set the water supply into its partial flow.
  2. Examine the fill valve if there’s unnecessary debris and clean it if needed.
  3. To avoid this problem, the rim hose should be properly linked to the fill valve and overflow.
  4. If the previous steps don’t work, you must replace the fill valve. Use the original one from Kohler.

6. Tank Refill Delay

  1. Before troubleshooting, you have to try fully opening the shut-off valve.
  2. After pressing the lever, the canister or flapper should be sitting in the right position. A loose chain or some other things may impede the flushing.
  3. You can try cleaning the valve inlet or valve seat, or seat washer.
  4. Make sure that there are no unwanted particles in the water supply.

Clogging Issues

As long as you have the right tools, you won’t have a hard time fixing clogging issues. Be particular with the differences between a flange plunger and a cup plunger. The internal cavity of a flange plunger is large, but it has a small mouth. Its business end should be against the drain of the toilet. Press it down to form a seal continuously until it releases the clog.

On the other hand, a cup plunger is typically used to clean the bathroom and sink drains. So, you better go with a flange plunger. If you have a stubborn clog, you must use a toilet auger. This tool has a long metal tube, handle on end, and claw on the opposite side. Use the claw to thread the bowl, then let the crank free the clog.


Be patient and mindful when dealing with Kohler Cimarron toilet problems & troubleshooting. You don’t always need to spend a lot of money when issues come up. You can try possibilities and use the proper tools. It’s best to do what you can do before finalizing with replacement or hiring a plumber. You can try the steps that you learn here and try to fix them yourself.
