How To Install New Sink Faucet

Replacing a sink faucet is a relatively simple plumbing project that can be completed in a few hours. Here are the steps on how to install a new sink faucet:

Turn off the water supply to the sink. There should be two shut-off valves under the sink, one for the hot water and one for the cold water. Turn both valves clockwise to turn off the water.
Disconnect the old faucet. There will be two nuts that hold the faucet in place, one on the hot water side and one on the cold water side. Use a wrench to loosen the nuts and then remove the faucet.
Clean the sink surface. Use a cleaner and a cloth to clean the surface of the sink where the new faucet will be installed.
Install the new faucet. Place the new faucet in the hole in the sink and then tighten the nuts on the hot water and cold water sides. Be sure to not overtighten the nuts.
Connect the water supply lines. Connect the water supply lines to the new faucet. The hot water line should be connected to the red or blue line, and the cold water line should be connected to the green or black line.
Turn on the water supply and check for leaks. Slowly turn on the water supply valves under the sink and check for any leaks. If there are any leaks, tighten the nuts on the faucet until the leaks stop.

Here are some additional tips for installing a new sink faucet:

Be sure to use a plumber's putty or Teflon tape to seal the connection between the faucet and the sink.
If you are installing a faucet with a sprayer, be sure to connect the sprayer hose to the faucet before you install the faucet in the sink.
If you are not comfortable installing a new sink faucet yourself, you can hire a plumber to do it for you.
