- Look to see if the chain or connection to the float arm has become disconnected. If it has, refasten it. If it is broken, it will need to be replaced.
- Jiggle the float arm. Sometimes that is all that needs to be done to get the water to stop running.
- Bend the float arm downwards slightly, if the water continues to run.
- Check the float ball, if there is one, to see if it is full of water. If it is, it will need to be replaced.
- Squeeze the clips and slide them down, if you have a float-cup assembly float system.
- Adjust the pressure-adjusting screw on the valve, if it has one. This will be located on the valve on the bottom of the tank.
How to Fix Toilet Float Problems
When a toilet continually runs, it is wasting water and raising the water bill. If you can hear water running, and haven't flushed the toilet for some time, there may be a problem with the toilet's float system. You will need to lift the lid off the tank of the toilet to gain access to the toilet float.
