How to Adjust a Toilet Fill Valve

Identifying the Fill Valve

The fill valve is a small valve located at the bottom of the toilet tank. It is responsible for filling the tank with water after each flush. There are two main types of fill valves:

• Ballcock fill valves: These valves are the most common type of fill valve. They consist of a ball that floats on the water in the tank. As the water level rises, the ball floats up and closes the valve, stopping the flow of water.
• Diaphragm fill valves: These valves are less common than ballcock fill valves. They consist of a diaphragm that is attached to a lever. As the water level rises, the diaphragm moves up and closes the valve, stopping the flow of water.

The fill valve is usually located near the back of the toilet tank, below the overflow tube. It is a cylindrical-shaped valve with a small stem that extends up into the tank.

Removing the Fill Valve

To remove the fill valve, you will need to:

1. Turn off the water supply to the toilet. The water supply valve is usually located near the base of the toilet.
2. Flush the toilet to drain the water from the tank.
3. Remove the tank lid. The tank lid is usually held in place by two screws.
4. Locate the fill valve. The fill valve is a cylindrical-shaped valve with a small stem that extends up into the tank. It is usually located near the back of the tank, below the overflow tube.
