How to Adjust the Ball Float in a Toilet

A ball float is an essential component of a toilet’s tank that controls the water level. It ensures that the tank fills up to the correct level after each flush. However, over time, the ball float may become misaligned or worn out, causing issues with the toilet’s functionality. Adjusting the ball float is a simple task that can be done without professional help. In this article, we will guide you through the process of adjusting the ball float in a toilet.

Here are the steps to adjust the ball float in a toilet:

1. Turn off the water supply: Locate the water shut-off valve, usually located near the base of the toilet. Turn it clockwise until the water supply is completely shut off.

2. Remove the tank lid: Lift the tank lid carefully and set it aside on a flat surface.

3. Identify the ball float: The ball float is a large, hollow plastic or metal ball attached to a metal rod or plastic arm. It is usually located on the left-hand side of the tank.

4. Adjust the ball float height: To increase the water level, bend the metal rod or plastic arm downward. To decrease the water level, bend it upward. Make small adjustments and check the water level after each adjustment.

5. Test the water level: Turn the water supply back on and allow the tank to fill up. Observe the water level, which should be around an inch below the top of the overflow tube. If the water level is too high or too low, repeat steps 4 and 5 until the desired water level is achieved.

7. Replace the tank lid: Carefully place the tank lid back onto the toilet tank and ensure it sits securely in place.
