How To Hook Up Plumbing Under Bathroom Sink

Remodeling a bathroom can be daunting if you're not handy with tools. However, one of the most common plumbing tasks is connecting the plumbing under a bathroom sink, and it's something that anyone can do with a few simple tools and a little patience.

Tools and Materials You'll Need

Before you start, gather the following tools and materials:

Wrench
Adjustable wrench
Plumber's putty
Basin wrench
Teflon tape
Faucet
Pop-up drain
Flexible water supply lines

Step-by-Step Instructions

Once you have gathered your tools and materials, follow these step-by-step instructions to connect the plumbing under your bathroom sink:

Turn off the water supply. The first step is to turn off the water supply to your sink. This is typically done by turning off the valves under the sink.
Disconnect the old faucet and drain. Once the water supply is turned off, disconnect the old faucet and drain. To do this, use a wrench or basin wrench to loosen the nuts that hold the faucet and drain in place. Once the nuts are loose, pull the faucet and drain free from the sink.
Install the new faucet. Now it's time to install the new faucet. Place the faucet in the hole in the sink and tighten the nuts that hold it in place. Be careful not to overtighten the nuts, or you could crack the sink.
Install the new drain. Next, install the new drain. Place the drain in the hole in the sink and tighten the nuts that hold it in place. Again, be careful not to overtighten the nuts.
Connect the water supply lines. Now it's time to connect the water supply lines to the faucet. To do this, use a wrench to tighten the nuts that hold the water supply lines in place. Be sure to use Teflon tape on the threads of the water supply lines to prevent leaks.
Turn on the water supply and check for leaks. Once the water supply lines are connected, turn on the water supply and check for leaks. If you find any leaks, tighten the nuts on the water supply lines or the faucet until the leak stops.

Congratulations! You have now successfully connected the plumbing under your bathroom sink. If you have any questions or concerns, be sure to consult a qualified plumber.
