Steps
Take the lid off the toilet tank and set it somewhere safe. Lift it straight up so it does not knock the flush valve.
Look at the fill valve, the tall unit with a float, and find the small adjustment screw on top or on the side.
Flush the toilet and watch the water level in the tank as it refills. Note where the water sits relative to the overflow tube.
Turn the adjustment screw with your screwdriver a small amount. On many Kohler valves, turning it one way lowers the shutoff level.
Flush again and check whether the water stops filling at a lower level. Repeat small turns until the valve shuts off cleanly.
Listen for the sound of water running after the tank fills. If it keeps running, turn the screw the other way or check the flapper.
Set the tank lid back in place gently and test one more flush to confirm the toilet stops running.
Tips and common mistakes
Turn the screw in small increments and test after each turn so you do not overshoot the correct level.
If the screw adjustment does not stop the running, the flapper or seal is often the cause, so check that next.
Keep the tank water level below the top of the overflow tube to avoid a constant trickle.
Turn off the water supply at the wall valve before reaching deep into the tank if anything feels loose.
Questions
What if my toilet has no adjustment screw?
Many fill valves use a float arm or a sliding clip instead of a screw. Adjust those the same way, in small steps, until the valve shuts off at the right level.
Why does the toilet still run after adjusting the screw?
A worn flapper, a bad fill valve seal or a stuck float can keep water running. Check the flapper first, since it is the most common cause.
How do I know the water level is right?
The tank should refill to about an inch below the top of the overflow tube and then stop. If it keeps filling past that, the valve needs more adjustment or repair.
