Bathroom Sink Water Line Connections

Installing a bathroom sink is a relatively simple plumbing project that even do-it-yourselfers can tackle. One of the most important steps is connecting the water lines to the sink. This may seem like a daunting task, but it's actually quite straightforward. Here are the steps on how to connect bathroom sink water lines:

1. Gather your tools and materials. You will need the following:

Adjustable wrench
Plumber's putty
Teflon tape
Two water supply lines
Faucet
Sink

2. Turn off the water supply. The first step is to turn off the water supply to the sink. This is usually done by turning off the valves under the sink. If there are no valves, you will need to turn off the main water supply to your home.

3. Disconnect the old water lines. If you are replacing an old sink, you will need to disconnect the old water lines. To do this, use an adjustable wrench to loosen the nuts that connect the water lines to the faucet. Once the nuts are loose, you can pull the water lines off of the faucet.

4. Apply plumber's putty to the new water lines. Take a small amount of plumber's putty and roll it into a rope. Then, apply the putty to the threads of the new water lines. The putty will help to create a watertight seal.

5. Wrap the water lines with Teflon tape. Take a few wraps of Teflon tape around the threads of the water lines. The Teflon tape will help to prevent leaks.

6. Connect the water lines to the faucet. Hand-tighten the nuts that connect the water lines to the faucet. Then, use an adjustable wrench to tighten the nuts further. Be careful not to overtighten the nuts, as this can damage the water lines.

7. Turn on the water supply. Once the water lines are connected, turn on the water supply and check for leaks. If there are any leaks, tighten the nuts further.

Tips:

If you are not comfortable working with plumbing, it is best to hire a professional plumber.
Be sure to use the correct size water lines for your sink. The size of the water lines will be specified in the sink's installation instructions.
If you are replacing an old sink, be sure to dispose of the old water lines properly.
