How to Replace a Kitchen Faucet

Kitchen faucet
Upgrade the looks and function of your kitchen with this step-by-step guide to replacing your kitchen faucet.

A good kitchen faucet can be the difference between loving your kitchen or loathing it. They can be attractive, a decoration in and of themselves. Faucets with features like pull-out sprayers can make washing dishes and rinsing fruits and vegetables a breeze. However, a kitchen faucet that’s old or worn can be an unsightly pain in the neck. Blain’s Farm & Fleet will help you replace your kitchen faucet in 9 easy steps. Every sink and faucet is a little different, so keep in mind that you’ll have to do some inspecting on yours to figure out exactly how everything is set up. If you run into any connection that’s soldered, contact a professional plumber to replace the faucet.

How to Replace Your Kitchen Faucet

1. Place a drain pan or bucket beneath the pipes you’re working on.

This will catch any water that leaks out of the pipes or tubing when you disconnect them. It will also be able to hold enough water to give you time to turn the water off if anything goes wrong and a fast leak emerges.

2. Temporarily remove anything from underneath the sink that will get in your way.

You’re probably going to be lying on your back and looking up at the bottom of the sink for most of this project, so give yourself some room. Also, space can get pretty tight beneath a sink. Getting anything out of the way that can be moved will save you a lot of frustration and wrist cramps.

3. Turn off and disconnect the water supply to the kitchen faucet. 

The oval knobs on the pipes are the water supply shutoff valves. Most of these knobs are marked with directions on which way and how far to turn them to turn the water off. Find which line is hot water and which is cold and mark them with some colored tape. After the water has all drained from the lines, you can remove the bucket or drip pan from under the sink.

4. Use a camping pad or anti-fatigue mat to lay down on. 

Don’t wreck your back on this project. You’ll probably be spending a lot of time under the sink, so give yourself some padding.

5. Remove the nuts, washers, and gaskets from the faucet inputs.

These usually require two pipe wrenches (one to hold and one to turn), and a flat head screwdriver (to pry stuck washers or gaskets free).

6. Remove the old kitchen faucet and put the new one in its place. 

Lift the old faucet straight up to avoid scratching your sink. You may want to clean the area where the old kitchen faucet sat before you put the new one in. Use plumber’s putty around the inputs of the new faucet. Just make a long snake and wrap it around the outside of each one. You can also use clear sealant. Fasten down all the gaskets, nuts, and washers. As you fasten, you’ll notice the excess plumber’s putty oozing out. Take this extra putty and put it back in the tub to use on your next project.

7. Connect the water supply to your new faucet. 

Since you marked your hot and cold water lines earlier, this will be a snap. Turn the water back on after you have everything reconnected and tightened down. Be sure to use Teflon tape on the threads of the connections to seal them.

8. Run a leak test.

Let the water run for 5 or 10 minutes on high and carefully inspect the faucet above and below the sink. The most common places for leaks are at the connections and around the base of the faucet, so check those spots carefully.

9. Clean up and replace everything you removed from beneath the sink. 

Dry up any water drops or puddles beneath your sink. They can cause rot and mold on your woodwork and cabinetry. While you’re under the sink, it might be a good idea to take this time to clean and organize that whole area.
