Identify the shut off valve

The shut off valve for a toilet is typically located under the sink or behind the toilet. It is a small, round valve with a handle. The handle may be located on the side of the valve or on top.

Turn off the water supply

To turn off the water supply, turn the handle on the shut off valve clockwise until it is all the way closed. This will stop the flow of water to the toilet.

Remove the old shut off valve

Once the water supply is turned off, you can begin to remove the old shut off valve. To do this, you will need to use a wrench to loosen the nuts that are holding the valve in place.

Install the new shut off valve

Once the old shut off valve is removed, you can install the new one. To do this, you will need to align the new valve with the existing plumbing and tighten the nuts that hold it in place.

Turn on the water supply

Once the new shut off valve is installed, you can turn on the water supply. To do this, turn the handle on the shut off valve counterclockwise until it is all the way open. This will allow water to flow to the toilet.

Test the new shut off valve

To test the new shut off valve, turn on the water to the toilet and flush it. The toilet should flush normally. If there is any problem with the new shut off valve, you will need to turn off the water supply and remove the valve. You can then troubleshoot the problem and try again.

Changing a shut off valve on a toilet is a relatively simple task that can be completed in a few minutes. However, it is important to follow the steps carefully to avoid any damage to your plumbing. If you are not comfortable doing this task yourself, you can always hire a professional plumber to do it for you.
