How to Replace a Kitchen Faucet

Prep work

The very first step in replacing a kitchen faucet is: get to know your sink. Clear everything from underneath the sink and check the number of holes it uses. A two-hole sink can sometimes accommodate a one-hole faucet, but you can’t fit a one-hole sink with a two- or three-hole faucet (a two-hole faucet has one hole for the faucet and a second hole for an accessory; the three-hole has separate hot and cold handles alongside the central tap). You should count the holes before investing in a new faucet, especially if you’re going for a different type than your current one.

Don’t forget that installing a faucet requires you to be on your back for the most part, and having a pillow makes the task more comfortable. A pan or towels to catch drips and safety glasses to protect your eyes from debris are also necessary. Make sure to turn off the power if you have an electrical outlet below the sink.

Why do you want to do it yourself? Is it to save money?

Most of us want to save money. So that may be the first reason that comes to mind. If so, you might want to think it through a bit more. First, how much, if any, will you really save? For example:

  • Do you have the right tools and supplies on hand or will you need to buy them?
  • Do you have “a bad back” or other ailments that might require chiropractic or physical therapy from laying on your back and maneuvering in awkward positions? Or even cause you to miss your real work?

Do you have the temperament to take on a DIY project that’s likely to be frustrating?

If this if your first DIY home project, it’s likely to be quite a challenge. Is your spouse, partner, children or other family members available to help hand you tools while you’re on your back? Are you easily frustrated? Do you take frustrations out on others? If loved ones nearby cover their ears or leave the room whenever you attempt a DIY project, that’s a clue.

Do you have the time to do it yourself?

Time is the one resource we can never recoup. Whatever time it takes you to complete this project is time away from other activities or memories you can be making.

Is whatever money you might save by doing it yourself worth time away from family, friends, fun? For myself, time with family is dear to me and one of my core values. That’s why I’ve chosen to not have a 24 hour service business.

Do you want to do it yourself because you enjoy tackling a challenge?

Hey, I get it! As a kid helping in my dad’s plumbing business, I enjoyed solving problems and helping people. Tackling a challenge and helping people at the same time made me feel like a hero!

So if you enjoy the challenge, are not easily frustrated, have a good back and the time to do it without sacrificing other more important activities — go for it!

I hope the tips I’ve included above help you avoid the common stumbling blocks I’ve mentioned.

Check New Faucet Connections

Now that our old faucet was removed we checked the new faucet connections for compatibility with our existing water supply lines.

Learn from our mistake!

You may want to do this beforehand so you don’t need to run back out to the home improvement store…again.

Our supply lines were SharkBite connections but the new faucet used traditional connection sizes (3/8 compression).

Hmm we weren’t sure what to do so…

So we called in reinforcements…

We called my dad who is a plumber for advice.

Since we had excess lines under the sink we used a zip tie and a small command hook to pull them together and hook them to the back of the cabinet to get the water lines out of the way.

This leaves a little more storage space under our kitchen sink.

How long will it take to install the faucet?

Replacing an existing faucet usually takes an hour or two — for the pros. If it’s your first time handling any sort of waterworks, it could easily take you more like eight hours, the equivalent of an entire day, to replace a kitchen faucet. You may also need to buy high-quality wrenches (including a pipe wrench), tube cutters, heavy-duty pliers and other tools required for the job, if you don’t already own them.

Cost

The cost to install a new kitchen faucet can vary greatly depending on whether you decide to install the faucet yourself or have a professional plumber complete the job. If you have the skills and all the tools required to install the kitchen faucet, then you will only need to worry about paying for the new faucet, which can cost about $50 to $2,000. However, if you don't have the tools for the job, you will need to purchase them before you can begin. This includes an adjustable wrench ($10-$40), channel locks ($10-$30), basin wrench ($15–$20), tape measure ($5–$20), plumber's putty or tape ($5–$10), and flexible supply lines ($3-$10).

On average, installing a new kitchen faucet will cost about $50 to $2,000, but if you hire a professional plumber for a more complicated installation, it can cost as much as $3,200 according to HomeAdvisor. The bulk of this price is due to the labor costs, which can range from $100 to $200 per hour, depending on the company, location, and difficulty of the installation.

With this in mind, if you can't handle the installation on your own and want to try and cut installation costs, it's recommended to opt for a simple stationary straight spout faucet with a chrome or stainless steel finish.

Steps on How to Replace a Kitchen Faucet

  1. Shut the water off to the faucet underneath the sink.
  2. Disconnect the water hoses from the shutoff valves.
  3. Loosen the nuts underneath the sink using the basin wrench.
  4. Cut the hose connecting the faucet to the sprayer with a pair of scissors.
  5. Carefully remove the old faucet off of the sink.
  6. Assemble the pieces of the faucet according to the instructions on the packaging. In general, it starts with a gasket that goes directly underneath the faucet and then a cover plate.
  7. Apply a thick glob of plumber’s putty underneath the cover plate and put the faucet into place. Be sure all the hoses connected to the faucet go through the center hole.
  8. Underneath the sink, slide the gasket, then the washer, and then the mounting bracket onto the faucet. Use a screwdriver to secure the bracket to the sink.
  9. Add a weight to the spray hose to allow it to retract when in use.
  10. Reconnect the hot and cold water hoses to the shutoff valves.
  11. If there is a fourth hole exposed from the old spray hose, use a cover plate or soap dispenser to block it. Add plumber’s putty to the underside and secure it to the sink.
  12. Turn the water back on.

Now install the new faucet

Follow any manufacturer’s preassembly instructions and place the optional flange (see Photo 8) over the faucet opening. Finger-tighten the flange nuts underneath the sink and check the alignment of the flange, faucet and sink hole from above.

Check the operation of the faucet and handle to confirm you’re not putting it in backward, and thread the feeder lines through the flange and sink holes. Then slip on the faucet washer, and thread on and tighten the faucet-mounting nut from below, gently spreading the faucet supply tubes if necessary to gain tool clearance (sometimes manufacturers provide a special tool for this).

Thread the spray nozzle line through the faucet body, then thread the spray hose fitting onto the faucet supply tube and tighten it. Pull the nozzle out of the faucet to make sure the hose under the sink operates freely, then attach the counterweight following the manufacturer’s instructions.

Tighten the new valves onto the supply tubes and mark the feeder lines just above the compression nuts on the valves for cut-off.

Photo 10: Connect the supply tube to the supply lines Clean the copper tubing with fine sandpaper, then slip the nut, compression ring and valve body over the pipe and tighten. Close the valve, turn on the main water valve and check for leaks. Place a bucket under the faucet and turn the faucet on to check for leaks. Reassemble the garbage disposer, P-traps and drain lines.

Follow the manufacturer’s directions to mount the new faucet, then remount the sink (with the new faucet) and hook up the water lines as we show in this how to replace a kitchen faucet project.

TIP With most faucets, only three of the four holes are covered, so you’ll either need to get a blank insert or use the extra hole for a liquid soap or instant hot water dispenser. Plan to do the installation while you’re under the sink with everything torn apart. If you have a leaking faucet, consult this article on how to fix a leaky faucet.

Selecting a faucet When you’re buying a faucet (as with most other things), you get what you pay for. Faucets that cost less than $100 may be made of chrome-plated plastic arts with seals and valves that wear. They’re OK for light-duty use but won’t stand up long in a frequently used kitchen sink. Faucets that cost more than $100 generally have solid brass bodies with durable plating and washerless controls that’ll give leak-free service for many, many years. Some even come with a lifetime warranty. Quality continues to improve up to about $200. Spend more than $200 and you’re mostly paying for style and finish. Stick with brand name projects so replacement parts will be easier to find—in the unlikely event you’ll ever need them.

Final Thoughts

Learning how to replace a kitchen faucet is one of the easier kitchen remodeling updates that DIYers can accomplish to freshen up their homes. While a new faucet can be installed in just a few hours, the type of faucet being swapped affects the amount of time, number of tools needed, and whether professional help may be optimal.

If you are updating a single-mount faucet with another single-mount, it is the easiest scenario. For those who want to change from a single-mount to a double-mount, holes will need to be created to accommodate the new faucet. Changing from a double-mount to a single-mount is also possible, but it requires a base plate to cover the holes that are no longer needed.
