It’s often assumed the toilet float will work seamlessly when it’s set up.
This is not always the case as the water level is reliant on the toilet float. If it is not set at the right height, this will create major concerns with the water.
A problem that often occurs is when a toilet float is not shutting off the water.
If a toilet float is not shutting off the water, this means the fill valve is compromised. It is likely damaged and needs to be replaced. To fix the issue, turn off the water supply, locate the fill valve in the tank, inspect for damage, and replace it with a compatible alternative.
This is the best way to make sure the toilet float does shut off the water and works the way it’s supposed to when needed.
This guide is going to show how to fix a toilet float that is not shutting off the water in your bathroom.

How To Fix A Toilet Float Not Shutting Off Water
1. Turn Off The Water Supply
You will want to begin by turning off the water supply.
Each toilet comes with a specific shut-off valve. This is designed to stop water from going into the toilet when it’s turned to one side.
You are going to find it near the toilet (usually behind it). When you do, turn the shut-off valve until the water stops streaming in.
When doing this, you will want to make sure it is done the right way.
This includes you don’t want a trickle coming through because you didn’t turn it enough. Make sure it is turned properly so water does not enter the toilet.
This is key as you will need to inspect the toilet and potentially replace the fill valve for it to work.
2. Locate The Fill Valve
The next step is to find the fill valve.
If the fill valve is not shutting off, you will need to find out where the part is. It is going to be located in the tank.
This part is responsible for how much water fills the tank. If it is damaged, the part is not going to adjust as it normally would.
This can lead to a significant mess with your toilet leaking or not working as it should.
This is going to be a long part on one side of the tank when you remove the lid. Inspect each part of the fill valve to see what’s going on.
3. Inspect For Damage
The most common reason for a toilet float not shutting off the water comes down to damage.
The fill valve can get damaged over time.
This type of damage could be something as simple as a hairline crack to one side. You will want to look through everything and take your time doing so.
The last thing you want is to miss the damaged spot.
When you do find the damaged part, it is common to want to fix it. This might be possible if it’s minor damage but most people are recommended to replace it.
You will not want to have to deal with this issue again.
4. Remove And Replace The Fill Valve
The last step is the most important one.
You are going to have to find a compatible fill valve for the toilet. This fill valve is going to replace the damaged one.
Be patient while doing this and make sure it’s anchored in the toilet tank properly. Otherwise, it will move and you are going to have the same issue again.
Due to the role of something like this, you have to be as patient as you can be. It’s the only way to do things the right way.
Final Thoughts
These steps will help fix a toilet float that is not shutting off the water.
If a toilet float is not shutting off the water, the most likely cause is a damaged or malfunctioning fill valve. To fix the issue, shut off the water supply, remove the tank’s lid, inspect the fill valve for damage, and replace it with a compatible alternative.
This is the only way to make sure the toilet float works the way it should.
If you don’t replace the toilet fill valve, you are going to have the same issue again. It’s best to avoid fixing the toilet fill valve and simply replace it.
