How to Replace a Toilet Supply Line

The toilet supply line is the hose that connects the water supply to the toilet. It’s a common plumbing problem for the supply line to leak or become damaged, and when this happens, it’s important to replace it as soon as possible.

Replacing a toilet supply line is a relatively simple DIY project, but it’s important to follow the steps carefully to avoid any leaks. In this tutorial, we’ll walk you through the process of replacing a toilet supply line, step-by-step.

Gather Your Tools and Materials

To replace a toilet supply line, you’ll need the following tools and materials:

• Adjustable wrench
• Pliers
• Tape measure
• Hacksaw
• Replacement supply line
• Pipe sealant

Shut Off the Water Supply

The first step is to shut off the water supply to the toilet. There are two ways to do this:

• Turn off the main water supply valve to the house. This is usually located near the water meter.
• Locate the shut-off valve for the toilet supply line. This valve is typically located behind the toilet, near the floor.

Once you’ve found the shut-off valve, turn it clockwise to close it. This will stop the flow of water to the toilet.

Disconnect the Old Supply Line

Now that the water supply is off, you can disconnect the old supply line. The supply line is connected to the toilet at the tank and at the wall.

To disconnect the supply line from the tank, you’ll need to use a wrench to loosen the nut that holds the supply line in place. Once the nut is loosened, you can pull the supply line out of the tank.

To disconnect the supply line from the wall, you’ll need to use a hacksaw to cut the supply line. Be careful not to cut the water line behind the wall.

Install the New Supply Line

Now that the old supply line is disconnected, you can install the new supply line. The new supply line should be the same length as the old supply line.

To install the new supply line, you’ll need to connect it to the tank and to the wall. To connect the supply line to the tank, you’ll need to use a wrench to tighten the nut that holds the supply line in place. To connect the supply line to the wall, you’ll need to use a pipe sealant to seal the connection.

Turn on the Water Supply

Now that the new supply line is installed, you can turn on the water supply. Turn the main water supply valve to the house back on. If you turned off the shut-off valve for the toilet supply line, turn it counterclockwise to open it.

Check the toilet to make sure that there are no leaks. If you see any leaks, tighten the connections until the leaks stop.

Replacing a toilet supply line is a relatively simple DIY project, but it’s important to follow the steps carefully to avoid any leaks. By following the steps in this tutorial, you can replace your toilet supply line with confidence.
