There is a common issue with Kohler toilets flushing slowly. If you are experiencing this problem, you may wonder what is causing it and how to fix it. 

Don’t panic! For troubleshooting and fixing the issue, take a look at our best troubleshooting guides. Let’s check out!

1. Kohler Toilet Clogging Problem

Clogged toilets are a common cause of poor flush performance in Kohler toilets. Several factors can cause a clogged Kohler toilet. 

Female hygiene products, baby wipes, and paper towels can cause this. These items do not break down like toilet paper and can quickly accumulate, leading to a clogged toilet.

Another cause of a clogged toilet is the buildup of waste over time. When the toilet is unused frequently, waste can dry out and become harder to flush. Also, hard water can accumulate minerals in the toilet bowl and pipes, causing blockages.

How To Fix:

If you’re having problems with your Kohler toilet clogging frequently, there are several potential solutions you can try!

i) Use A Plunger Or A Auger:

The most common way to remove a clog is to use a plunger. Place the plunger over the drain opening. Then, pump it up and down several times. This can help create suction and dislodge the clog. 

But if a plunger does not work, you can try using an auger. This tool has a long cable with a corkscrew-like end that can help break up clogs in the toilet.

ii) Essential Cleaners:

There are several chemical cleaners available that can dissolve clogs in the toilet. However, these cleaners can be harsh and should be used with caution. Follow the manufacturer’s instructions carefully and avoid mixing different cleaners.

If hard water buildup is a problem, consider installing a water softener. This can help prevent mineral buildup in the toilet bowl and pipes.

iii) Regular Cleaning:

Regular cleaning of the toilet bowl can help prevent clogs. Use a toilet bowl cleaner specifically designed for toilets and a toilet brush to clean the bowl.

How To Unclog A Kohler Toilet

A clogged toilet is a common problem in any household, but it can be especially frustrating when it comes to a Kohler toilet. Here are some steps to follow in order to unclog a Kohler toilet:

Step- 1: Turn off the water supply to the toilet if the water level is rising and the toilet is in danger of overflowing. Then, put on a pair of rubber gloves and ensure that you have a flange plunger, as it works best for toilets. If the plunger is dry, moisten it with water.

Step- 2: Place the plunger into the toilet bowl and ensure that it covers the entire drain opening. Use both hands to hold the plunger handle and gently press down. Push and pull the plunger up and down with force for approximately 20-30 seconds. This will create suction and dislodge the clog. Be careful not to break the toilet bowl.

Step- 3: Flush the toilet to check if the clog is cleared. If the toilet flushes properly, turn the water supply back on and allow the toilet tank to fill up. If not, repeat the plunging process a few more times.

Step- 4: Use a toilet auger if the plunger fails to remove the clog. Put the auger through the drain pipe and into the bowl according to the manufacturer’s instructions. Twist and turn the auger handle to clear the clog.

Step- 5: Pour hot water into the toilet bowl if the plunger and auger do not work. Do not use boiling water, as this can damage the toilet. The hot water can help to dissolve the clog and remove it. 

If none of the above methods work, it may be time to call a plumber. They have the tools and expertise to unclog the toilet.

2. Kohler Toilet Flapper Not Sealing

The most common reason a flapper does not seal properly is wear and tear. As the flapper ages, it can become warped or distorted, preventing a tight seal. Other reasons for a flapper not sealing properly include mineral buildup, debris, and incorrect installation.

In fact, hard water can cause mineral buildup around the flapper, preventing it from sealing properly. Dirt, sand, or other particles can get trapped between the flapper and the flush valve seat. Finally, if the flapper is not installed properly, it may not seal correctly
