The majority of homeowners don’t make this error twice!

If you want to prevent floods and operate effectively, you must close the valve that controls the water supply.

However, occasionally you’ll discover that the valve won’t entirely close. What’s worse is that this may lead to significant leaks, which significantly raise your water expenses.

If a shut-off valve is malfunctioning, you’ll either need to repair the broken parts or the valve itself.

DISCONNECTING THE TOILET VALVE You can try a few fast repairs to try to close the valve. They’re less dangerous and easier than clearing your toilet of clogs. You don’t have to be afraid.


Sometimes a little bit of movement is all you need.

You should at least once a year turn the toilet valve on and off as part of routine bathroom maintenance. This prevents it from becoming trapped.

If you haven’t been doing that, you might simply have a valve that is a little sticky.
The valve should be turned clockwise, counterclockwise, and back again carefully and gently. Use moderate force so as not to harm the components.

Usually, this will be sufficient to get rid of any accumulated dirt or grime. The valve should become slack enough to turn easily after a few minutes of wriggling.

After that, you can close the valve.
This should be your initial strategy, but if it doesn’t work, the other strategies will be helpful.
WD 40

Utilizing a lubricant like WD 40 is one choice. Because it won’t harm the metal or rubber parts of the valve, WD 40 tends to operate better than other lubricants.

When a valve will turn just a little bit but you can’t manage to loosen it with your strength alone, lubricant can be useful.
Spray a lot of lubrication on the valve. Make sure you adhere to all handling and breathing safety recommendations.
Ten minutes should be given for the WD 40 to work. The valve can then be turned with your hands once more.


If you want to open the valve without utilizing a spray, hot water can be appealing. Since metal tends to be more pliable and simpler to move while warm, it is suitable for very cold metal.

You run the risk of breaking the cold valve if you are too aggressive.

Put on rubber gloves, fill a bucket with hot water, and soak a cloth in it. To loosen your cold water line, place the hot cloth on top of the valve.

To transfer the heat, let the towel there for a while.
Another method is to heat the valve using the hot air from a hairdryer.
SCREW IN THE CENTER TIGHTEN Sometimes the problem is simply a loose center screw. The most crucial part of the valve is the middle screw.
It is in charge of securing all the parts together.

Your valve can leak or become unable to seal correctly if the center screw becomes loose. After tightening the screw using pliers, attempt to close the valve once more.

A toilet valve that won’t shut off? How can you fix it?

If none of the solutions mentioned above work, you might have to completely replace the valve. You’ll need to perform a little more labor-intensive task because you can’t shut off the water at the valve.

KEEP YOUR MAIN WATER SUPPLY OFF If the main water supply isn’t switched off, you can’t work efficiently. Otherwise, removing the valve could result in leaks and flooding.

Shutting off your main water supply should be easy if you already know where it is. For those who are unsure, the laundry room, basement, or area under the kitchen sink are the most typical locations.

You can start working after turning off the water.

EXCESS LIQUID MUST BE REMOVED FROM PIPES. The liquid in your supply line will still be present. You risk having water overflow from your pipes, drain, and toilet tank if you don’t drain it before removing the valve.

Check the valve on your toilet. Find a faucet that is mounted lower than the valve by doing so. Switch it on.

Your drainage system will receive the water as it flows out of the pipes. You will know that the excess liquid has been dealt with when the faucet runs dry.

CUT OFF THE TOILETS’ SUPPLY LINE. A supply pipe is also there for your toilet. Basically, this is just a hose that transports water from the toilet to the valve.

This will involve a little more mess. You’ll need a bucket to collect the water because it’s difficult to shut off this supply pipe using a faucet.

Place the bucket beneath the valve so that water can enter it directly.
The supply line that is attached to the valve should be easy to identify. It will dash to your bathroom.
The connection bolt can be loosened and removed with a crescent wrench. then remove the line.
Water should start to drain from the supply line of the toilet. It shouldn’t be a problem if you have a big enough bucket.

THE BROKEN SHUT-OFF VALVE MUST BE REMOVED Finally, you can remove the damaged valve. Depending on whether your connection employs compression joints or copper pipes, the removal process will be different.

Joints in compression:

To prevent the pipe from turning, grip it steadily with a set of pliers. The bolt holding the valve to the pipe should be removed using the crescent wrench. When the bolt is loose, remove the valve. Copper pipe:

Use a pipe cutter to cut through the damaged valve and remove it. Clean up by using a tube cutter. The more of the pipe you leave alone, the better. The installation will be simpler with longer pipes. PUT YOUR NEW SHUT-OFF VALVE IN Connect the pipe with a compression nut. To the ring, fasten your replacement valve. Utilizing your crescent wrench, tighten the compression nut and stem threads. The supply line can then be reconnected to the toilet at this point. After that, you can turn on your main water supply to check the connection’s functionality.

A Shut Off Valve Can It Fail? A shutoff valve may malfunction and require replacement. In actuality, it is unlikely that these valves will endure forever.

Between 15 and 25 years normally pass before they need to be changed.
But if you don’t switch your valve on and off once a year, you can encounter problems. This is a crucial component of toilet maintenance.
If the valve isn’t occasionally moved, rust will build up on it. Turning will be impossible as a result, and potential leaks may develop afterwards.

WHY IS THE LEAKING TOILET SHUT OFF VALVE? Various factors might cause toilet shutoff valves to leak. Usually, you can fix the faulty part or the valve instead of having to replace the complete toilet.

The following are the most typical causes of valve leaks:

The valve has outlived its usefulness and is old and dirty. It cannot fully close because it has been trapped. The valve hasn’t been adequately maintained. It should be switched on and off once a year. It could rust if this maintenance is skipped, which would make it difficult to turn and close. The valve has developed damage or a broken component. This has caused leaks or a failure to seal. You must identify the leak’s source in order to efficiently fix your valve.

CONCLUSION Being a homeowner whose toilet shut-off valve won’t shut off can be incredibly distressing. You can waste hundreds of gallons of water if your water is left running as the hours and days mount up.

When the utility bill arrives, your wallet will thank you more if you take care of the problem right away.
Fortunately, changing your toilet shut-off valve is frequently extremely simple. Depending on the cause, the replacement strategy will change a little.
The most frequent cause, however, is an issue with your rubber washer. In these circumstances, you can just swap out that component.

You can also hire a plumber if you have replaced your shut-off valve and are still experiencing issues or are unsure of where to begin. The cost of a plumber may seem high, but it is nothing compared to the water bill you can incur if you leave the toilet running for an extended period of time.
