10 Kohler Cimarron Toilet Problems And Solutions
Don’t let issues on your Kohler Cimarron toilet frustrate you. Instead, take time to troubleshoot your toilet to uncover the causes of the problems and then solve them.
Below is a detailed examination of what could be wrong with your toilet and its solutions.
Kohler Cimarron Toilet Flushing Problems
Flushing is one of the most annoying and frustrating problems you can have in your toilet. Everyone deserves an efficient flushing toilet that drains the waste with minimal effort using little water.
For that reason, it’s of utmost importance that you swiftly solve any flushing problems in your Kohler Cimarron.
a) Poor Flush
Your Kohler Cimarron toilet’s chain likely has too much slackness, or the hose isn’t well-connected to the top of the canister if it flushes poorly. Moreover, something could be obstructing the trapway or under the rim holes, or there’s a problem with the waterline.
Fix
- If the chain has too much slackness, take out a link or two.
- Ensure the hose is connected correctly to the top of the canister.
- Connect the line designated to your toilet is well-connected to make sure the water reaches your Kohler Cimarron toilet.
- Clear the trapway to get rid of any obstructions.
- Clean the holes under the rims of your round or elongated toilet.
B) Kohler Cimarron Toilet Won’t Flush
Your toilet won’t flush if the chain isn’t connected.
Fix
Reconnect your toilet chain and adjust it to attain the right slackness. In addition, make sure the trip lever is parallel to the top of the tank, and the trip arm bracket stays flat on the interior of the toilet.
Ensure the trip arm bracket is also vertically positioned when on the tank’s bottom.
c) Noisy Tank During A Refill
Debris in the fill valve will make your toilet tank generate noise during a refill.
Fix
To get rid of the noise in your toilet tank during a refill, put the water supply to your toilet to partial flow, check the fill valve for unnecessary debris and, if needed, clean it. You can avoid this problem by properly linking the rim hose to the overflow and fill valve.
Install a new fill valve if the solution above doesn’t fix the problem. Buy an original fill valve from Kohler.
D) Kohler Cimarron Toilet Keeps Running
The fill valve is responsible for refilling the tank after a flush and controlling how much water goes into the tank. Water shouldn’t flow into your toilet non-stop, so examine the fill valve if that happens.
Fix
Troubleshoot this issue by cleaning the seat of the fill valve or replacing the fill valve. Fill valve replacement is the best solution if nothing happens after you lower the water level of the tank.
Furthermore, make sure the trip arm bracket and the flange are parallel to the tank’s top.
e) Delayed Toilet Refill
Dirt or unwanted particles in the valve seat or valve inlet, seat washer, or water supply can cause this issue. Additionally, it can happen due to a loose chain.
Fix
Remove dirt or unwanted particles in the valve seat or valve inlet, seat washer, or water supply. Moreover, press the lever and ensure the flapper or canister is in the correct position.
Before troubleshooting, try to open the shut-off valve completely.
f) Water Flowing Periodically
You will encounter this issue if the seal is worn-out or dirty. A damaged or misaligned flush valve seat can also cause the problem.
Fix
- Adjust the chain to have the proper slack to ensure the seal doesn’t get stuck with the seat of the flush valve.
- Adjust the level of water when your toilet overflows because leakage can be a serious problem.
- Clean or replace the seal.
- Replace the flush valve seat.

Loose Handle
Two things can cause a loose handle in your Kohler Cimarron toilet. These are:
- The flush lever or the lift wire that connects the ball seal to the handle is broken or unattached.
- The handle mounting nut inside the tank is loose.
Fix
- Lift the toilet tank lid and check inside.
- Reconnect the chain or wire joining a plug found at the tank’s bottom, and the toilet handle. You will need an adjustable wrench to tighten the mounting nut.
Broken Handle
A plastic handle is more susceptible to breaking than a metal one, so you are better off if your toilet has a metal handle. However, they are equally at risk of accumulating lime build-ups, dirt, and dust which typically happens around the mechanism of an interior tank, the handle threads, and the interior nut.
Fix
Wipe the threads and nuts using vinegar to eliminate the grime accumulation. If the handle hangs vertically, you will need to replace it.
Too long or disconnected chain
A disconnected chain or one that’s excessively long makes the handle loose, causing your toilet not to flush.
Fix
- Examine inside the toilet tank to see if the chain is connected to the flapper and hooker lever.
- If you find out that the chain is too long, put the end of the chain in a higher pole. Flush the toilet to test the adjustment and ensure you have resolved the problem. If the issues persists, continue adjusting the chain.
Clogged Kohler Cimarron Toilet
Toilet clogs stem from various problems, including sewer line or toilet trap clogs, flushing tissue paper and other non-flushable stuff, or blockage in the toilet vent. Ultimately, fixing a clog isn’t an issue if you have the proper tools.
How To Unclog A Kohler Cimarron Toilet
You need to know which plunger to use to unclog your Kohler Cimarron toilet. Cup plungers come in handy when unclogging bathtub and sink drains.
On the other hand, flange plungers are designed with a bigger internal cavity and a tinnier mouth and are excellent for unclogging toilets. Follow the steps below to unclog your toilet.
- Ensure your Cimarron toilet bowl has standing water.
- Wear rubber gloves.
- Ensure you fully pull out the toilet plunger’s flange from the cup.
- Insert the toilet plunger into the toilet bowl, making sure the cup fills up with as much water. Lower the plunger at an angle.
- Forcefully push down the plunger’s cup and back up without breaking the seal. Repeat the motions until the clog is cleared.
