How to Fix a Running Toilet Fill Valve? If your running toilet is caused by a fill valve that needs adjusting, follow these steps:
1. Turn off the water at the shutoff valve behind the toilet. Flush the toilet to empty the tank.
2. Remove the lid from the tank and check to see if the water level is set too high. If it is, turn the adjustment screw on the fill valve clockwise until it stops. Flush the toilet and check for leaks. Repeat this step if necessary.
3. If your fill valve has a float arm, bend it so that the float ball sits lower in the tank. This will allow less water to enter and should stop your running toilet problem.
- The most common reason a toilet fill valve runs constantly is because the float ball is set too high
- To fix this, turn off the water to the toilet at the shut-off valve and flush the toilet to empty the bowl
- Then, remove the lid from the tank and adjust the water level by turning the adjusting rod clockwise to lower it or counterclockwise to raise it
- If your fill valve has a screws on top of it, you can also try adjusting these to change how high or low the float ball sits in relation to the water line
- If your problem persists, there may be something wrong with the flapper or flush valve mechanisms that are causing water to constantly enter into and exit out of your tank without fully filling it up each time
- Try inspecting these parts for any damage or debris that could be causing them not to seal properly and preventing your tank from holding enough water

Toilet Fill Valve Won’T Shut off

If your toilet fill valve won’t shut off, it’s likely due to a problem with the float. The float is a component of the fill valve that controls how much water flows into the toilet tank. If the float is stuck in the “up” position, it will prevent the fill valve from shutting off properly.
To fix this problem, you’ll need to adjust or replace the float. In most cases, adjusting the float is all that’s needed to fix a toilet fill valve that won’t shut off. To do this, simply bend the wire that connects the float to the fill valve until the float sits at the proper level in relation to the water line.
If your toilet has a plastic ball float, you may need to unscrew it from its housing and adjust it accordingly. If adjusting or replacing the float doesn’t solve your problem, there may be an issue with debris caught in the fill valve itself. Use a toothpick or other small object to clear any dirt or grit from inside of the valve body.
Once you’ve cleared away any obstructions, reassemble everything and give it another try
– your toilet should now function properly!

Toilet Fill Valve Problems
If your toilet isn’t filling up correctly, or if it’s taking longer than usual to fill up, there may be a problem with the fill valve. The fill valve is responsible for bringing water into the tank, so if it’s not working properly, your toilet won’t function correctly.
There are a few different things that could be causing your fill valve problems.
First, the float could be set too low. This means that when the water level in the tank drops, the float doesn’t trigger the fill valve to turn on and bring more water in. To fix this, simply adjust the float to a higher setting.
Another possibility is that there is something blocking the Fill Valve from opening all the way. This could be debris or sediment buildup, which can happen over time. If this is the case, you’ll need to clean out the Fill Valve to clear any obstruction.
Finally, it’s possible that the Fill Valve itself is damaged or broken and needs to be replaced. If you’ve tried adjusting the float and cleaning out any obstructions but your toilet still isn’t functioning properly, then it’s time to replace the Fill Valve with a new one.
