Adjusting the float may be necessary to change water levels in the toilet.

Kohler toilets, like all others, have a float on the inside. The float controls the flow of water coming into the toilet after a flush. Water rising inside the toilet lifts up on the float. When the toilet reaches a certain height, the flow of water will stop. Adjusting the toilet float is necessary when there is running water long after the toilet is flushed, or if you wish to lower the amount of water used when you flush the toilet.

Step 2

Locate the float ball, which is attached to a brass arm. Locate the screw at the end of the brass arm.

Step 3

Turn the screw counterclockwise using a screwdriver and lower the float arm once the brass arm is released.


Step 4

Hold the brass arm of the float and flush the toilet. Allow the float arm to rest on the water as it rises and find the right level of water for your toilet. Tighten the screw to lock the float arm in place.


Do not bend the brass arm of the Kohler's float. Always use the adjustment screw.
