How to Install a Kitchen Faucet

Installing a new kitchen faucet is a simple task. While you should follow the manufacturer’s instructions throughout the process, these general tips will also help you get the job done.

Step 1: Check Your Existing Faucet

Are you replacing your current faucet? If so, check beneath it before purchasing a new one. Count the number of mounting holes. This will determine how many mounting holes you should look for when you purchase your new faucet.

It’s worth noting that a one-hole faucet can still be installed in a three or four-hole layout with the help of a deck plate. However, three or four-hole faucets cannot be installed in a one-hole layout. Consult with a professional if you’re not sure which type is right for your needs.

Step 2: Remove the Current Faucet

You need to remove your existing faucet entirely before beginning to install a new one.

Shut off all water valves to the sink. Turn on the faucet to release any built up water.

Take this time to examine your supply tubes and overall plumbing layout. If the tubes appear to be in poor condition, consider replacing them when you install your new faucet. It’s also smart to take a picture of the layout so you know how to make the proper connections later.

Place a bucket beneath the supply lines and tubes as you disconnect them. This helps catch any water that might spill out.

For your own safety, have someone hold the faucet securely as you remove the nuts from below. Use a basin wrench for this step.

Once the faucet is loose, carefully remove it by lifting it up and out. You may also want to clean the sink before installing the new faucet if necessary.

NOTE: It may also be necessary to disassemble the garbage disposal if you have one. Refer to the manufacturer’s instructions to learn how.

Step 3: Install the Gasket & Faucet Lines

Refer to the manufacturer’s instructions to install the gasket or flange over the faucet hole. Next, insert the faucet with connected lines into the hole. From below, check to ensure the feeder lines are through the hole and spread out enough to not crowd out your tools. Install the faucet washer and faucet-mounting nut. Tighten the flange nuts as well.

Step 4: Make Connections

Connect supply tubes to supply lines. If your faucet has a spray nozzle, remove the nozzle head before turning the water on to ensure it can move freely and easily. You may need to adjust the position of the lines/tubes if it cannot.

NOTE: It might be helpful to use plumber’s tape during this step. Keep it on hand in case you need it.

Step 5: Test

Once all connections have been made and every component is tightly secured, place a bucket under the faucet and slowly turn the water back on. Look for any signs of leaking. Tighten any loose connections if you do spot a leak.

If everything works well, reassemble the garbage disposal if applicable.

Step 6: Clear Your Lines

Your new faucet may have an aerator. If it does, remove it from the faucet and let the water run for a few minutes. This helps clear the lines. During this time, continue checking all lines and tubes for signs of leaking. Tighten the connections wherever necessary. After a few minutes, place the aerator back in position.

The specifics of the process may vary from one faucet to another. Again, that’s why it’s important to check the manufacturer’s instructions every step of the way.

That said, the these basic steps will generally apply no matter what type of faucet you’re installing. It’s an easy task that doesn’t require much time or supplies. Although a plumber can help if you’re not confident in your own abilities, this is probably a job you can handle on your own.
