How to Fix a Kohler Toilet That Won’t Stop Running?

In six simple steps, you can fix your Kohler toilet that won’t stop running. So, let’s dive in:

Step 1

Remove the toilet tank lid and set it aside.

Step 2

Locate the black float inside the toilet tank and jiggle it slightly. This is typically all that needs to be done to fix a Kohler toilet that won’t stop running. This is because the float can get stuck.

Step 3

If you find that jiggling the float isn’t working, you need to locate the plug that seals up the hole in the bottom of the tank and reach in to make sure that it’s tightly sealed. If the plug is properly sealed, the water will stop running in the toilet and fill the tank, which will lift the black float and stop the inflow of water.

Step 4

If you find that the plug isn’t sealing properly, there’s more that you need to do. Remove any debris that might be sitting around the exit seal of the toilet tank – this is the same plug that you just worked with – and see if that allows the plug to properly seal.

Step 5

If the plug isn’t the problem and the water is still running, you might need to replace the float assembly. If this is necessary, you need to unplug the hose that’s connected to the top of the float assembly. Once that’s done, you unscrew the float assembly and remove it from the toilet’s tank. To install the new float, you simply screw the float where the old one was before and plug the hosing into the new float.

Step 6

You might have to install a new seal at the bottom of the toilet tank if none of the other steps above worked. To do this, you need to shut off the water to the toilet, pry off the old seals, and snap the new seals into place.

How Do I Adjust My Kohler Toilet?

A tank must have the right amount of water in it to ensure that the toilet flushes properly and doesn’t continuously run. Kohler toilets have water level indicators located on the flush valve or tank wall. You can raise or lower the water level by adjusting the tank’s float.

First, you need to know what kind of fill valve you have in your toilet, then follow the steps to adjust the water level in your tank.

Older Style

You’ll know that you have the older style toilet fill valve if the float attachment is horizontal in the tank. To adjust this style of toilet fill valve:

  • Squeeze the metal C-shaped clip on the float valve attachment; this is called the Float Valve Adjustment Clip. Then slide that metal clip left or right on the float attachment to adjust the water to the level you want. Using a pair of pliers can make this process easier.
  • After adjusting the water level, flush the toilet to verify that the water rises to the marked water level.
  • If the water isn’t where you want it to be, repeat steps 1 and 2 until the right level has been achieved.

Newer Style

You’ll know that you have a newer style fill valve if the float attachment is located in one corner of the toilet. To adjust this fill valve style:

  • Locate the screw connected to the float arm, then start by turning it one full turn. You can do this using a screwdriver or your hand.
  • Turning the screw clockwise will raise the water level.
  • Turning the screw counterclockwise will lower the water level.
  • After adjusting the water level, flush the toilet to make sure that the water level is where you want it to be.
  • If the water isn’t where it’s supposed to be, repeat steps 1 and 2 until it is.

Conclusion

Having a Kohler toilet that runs constantly is not only annoying but is costing you a lot of money in utilities. How to fix a Kohler toilet that keeps running has a simple answer to it, and if you follow the steps listed in this article, you’ll be set.
