How to Install Kitchen Faucet

There are a lot of DIY projects that the average homeowner can do, and upgrading your faucet to a newer model is one of the easier and more functional things. You can pick out the new faucet at the local hardware supply store, or simply order one online, and then you can put it in yourself without too much trouble. 

There are some things to keep in mind when working, and you’ll want to make sure you have done all appropriate prep and have all your tools ready and waiting, but it can be done in a short amount of time and with little special skill. Here’s what you need to know about how to install a kitchen faucet.

How To Install A Kitchen Faucet


Be sure your new faucet fits the sink holes you have. Also, make sure you have a good hands-free flashlight, and since you’ll be on your back, some sort of back support like a pillow is ideal. Other items to have handy include a pan for drips, some old towels, and of course, personal safety equipment like safety goggles. Be sure you’ve cleaned out underneath the sink area, and cleared any debris as well. Shut off the power to the sink and the surroundings.

Shut Off The Water & Disconnect Supply Lines

Underneath the sink area there should be at least one, but more commonly two, shutoff valves. Make sure that these valves have been turned completely off, generally requiring at least a one-quarter turn clockwise. Sometimes the valves may be stuck, which may require tools to improve the grip to turn. Follow the supply lines to the base of the faucet, and remove them. 

Disconnect The Old Faucet & Remove

The faucet will be held in by one or two large nuts, which need to be removed to take the faucet out. These can usually be removed easily with a standard adjustable wrench. Once the supply lines and anchor nuts have been removed the faucet should be able to be removed.

Install New Faucet & Connect

Place the new faucet in the same place as the old one, and the connections underneath should be roughly the same. There will be pipe nipples to accept the water supply lines, be sure those are tightened down sufficiently. Double-check the instructions to ensure you do not miss any anchoring points.

Anchor Valves

On the underside of the new faucet will be space to attach the anchoring nuts to the bottom of the valves. These are important, to include, and the faucet cannot be reliably or properly mounted without anchoring the valves.

Turn On Water Supply Lines

Turning back on the water supply lines is often the “moment of truth” for those who may doubt the seal of their supply line attachments. Once the water has been turned back on and allowed to pressurize, there should be no sprays, drips, or other leaks.

Tips For Installation

  • The number of holes in your countertop, and their placement, determine what faucets you can put in.
  • You will need to know the distance between the two holes in your countertop.
  • There are many types of handle and spout configurations, make sure you get one suited to your needs.
