How to Adjust Toilet Float Less Than 5 Minutes

Toilet float is an important part that controls the amount of water in the toilet tank. It moves with the water level, opens the filling valve after flushing and closes the valve when the tank is full. Adjustments to the toilet float may be needed when the toilet fails to flush completely, which usually because there is not enough water in the tank or when the toilet keeps running because the water level is too high. There are two common types of toilet floats and each type has a method to adjust. Here we show you how to adjust toilet float less than 5 minutes by yourself easily. 

Part 1: How to Adjust Toilet Float Ball – Traditional Model Toilet

The ball in the toilet is also known as a toilet float which is attached to a long metal rod that connects the toilet fill valve. It has been a staple in toilets for decades and there are many toilets still use it to regulate how high the water level fills into the toilet tank. You need to adjust toilet float if there isn’t a correct water level in the tank. Follow the steps below to adjust the toilet float ball.

Step 1: Remove the toilet lid and set it aside carefully. Most tank lids are made of ceramic and can crack if dropped. 

Step 2: Find the toilet ball in the toilet tank. If the tank is full, it will float on the top of the water. 

TIP : If the tank is full and toilet ball has sunk or there is some water in the ball, it is no longer useful and you need buy a new one and replace it.

Step 3: Find an adjusting screw at the connecting part between ball rod and toilet fill valve.

Step 4: If the toilet is running all the time, the ball is sitting too high in the tank and needs to be lowered. Turn the screw counterclockwise with a screwdriver until the water stops running. If the ball is too low in the tank and is not adequately flushed, you need to raise the ball by turning the screw clockwise.

TIP : If you don’t have a screwdriver, you can grasp the toilet ball arm in your hands and slightly bend it upwards to raise the ball, or bend it down slightly to lower the ball.

Step 5: Flush the toilet and let the tank refill to check the water level. The water level should be 1-1.5 inches below the top of the overflow tube.

Step 6: If the water level is proper, reinstall the tank lid. If not, check How to Fix A Toilet That Keeps Running with 3 Steps and 6 Reasons Your Toilet Won’t Flush & 6 Solutions to Fix It.
