How To Install Supply Line Bathroom Faucet

Installing a bathroom faucet supply line is a relatively simple plumbing task that most DIYers can complete in an hour or two. However, it's important to follow the steps carefully to ensure a leak-free installation.

Before you begin, gather the following tools and materials:

Adjustable wrench
Pliers
Faucet supply lines
Teflon tape
Bucket or bowl

### Step 1: Turn off the water supply

The first step is to turn off the water supply to the faucet. This is usually done by closing the shut-off valves located under the sink. If there are no shut-off valves, you will need to turn off the main water supply to your home.

### Step 2: Disconnect the old supply lines

Once the water supply is turned off, you can disconnect the old supply lines. To do this, use an adjustable wrench to loosen the nuts that connect the supply lines to the faucet and the shut-off valves. Once the nuts are loose, you can remove the supply lines by hand.

### Step 3: Install the new supply lines

Take the new supply lines and wrap a few layers of Teflon tape around the threads. This will help to create a watertight seal. Then, screw the supply lines into the faucet and shut-off valves. Tighten the nuts using an adjustable wrench, but be careful not to overtighten them.

### Step 4: Turn on the water supply

Once the supply lines are installed, you can turn on the water supply. Slowly open the shut-off valves and check for leaks. If you see any leaks, tighten the nuts on the supply lines until the leak stops.

### Step 5: Finish the installation

Once the supply lines are installed and leak-free, you can finish the installation of the faucet. Follow the manufacturer's instructions to complete the installation.

### Conclusion

Installing a bathroom faucet supply line is a relatively simple task that can be completed in an hour or two. By following these steps, you can ensure a leak-free installation.
