How To Install a Kitchen Faucet

When You Should Call a Plumber

What should be a 2-hour faucet-replacement job can quickly turn into an entire weekend plumbing project if you are faced with surprises along the way. If you don’t have plumbing experience or encounter a complication, it’s often better to call a plumber than to attempt to remove and reinstall additional plumbing elements.

  • You have a wall-mounted faucet. Faucets that attach directly to the wall behind the sink are among the newest and trendiest faucets around, appealing to those who want Old World appeal as well as those who are looking to create a semi-pro chef’s kitchen by installing a wall-mount faucet with a rotating and extending faucet arm. Unfortunately, this is one of the most involved replacements a homeowner can attempt. Making the switch from a sink-mounted (or countertop-mounted) faucet to a wall-mounted faucet involves opening up the wall behind the sink and running new water-supply lines, which is definitely a job for a plumber. Plus, to get rid of the faucet holes left behind, they will need to replace your sink or countertop.
  • You need to remove additional plumbing to access the old faucet. Sometimes, you simply can’t wedge your body far enough beneath the sink to have a clear path to reach the nuts holding the old faucet in place. When it looks like you’ll have to remove additional plumbing like the sink drain trap or the garbage disposal, it can start to get more complicated in a hurry. A professional plumber can help.
  • You don’t have enough time to complete the project. For those who don’t have a lot of experience with plumbing or do not have the extra hours to spend learning how, it may be a good idea to call a plumber for help.
  • You installed the new faucet, but it’s leaking and you don’t know why. If you’ve successfully installed the new faucet, but testing it uncovered a leak, it’s time to investigate and fix the issue. If you’ve checked all of the connections, and can’t figure it out, it’s probably best to ask for help from a professional plumber. A slow leak can cause a great deal of damage over time.

Critical Steps Before Replacing a Kitchen Faucet

  • 1. Know where your main water shut off valve is located and how to shut it off in an emergency. Make sure everyone in your home knows too. (read more on how to find and turn off your home’s main water valve). If your faucet’s stop valves were to break off or not function, you will need to quickly shut off the water at this main water shut off valve.
  • 2. Inspect your faucet’s dedicated stop valves (also known as shut-off valves). They’re usually either straight or angled knobs made of metal that protrude a few inches inside the cabinet. 
  • 3. These stop valves are critical because they’re used to shut off the water to only that faucet (or other water fixture) without needing to turn off the main water to the entire building. So if the stop valves are old, you’ll need to replace them before removing the old faucet. If they need to be replaced, add them to your shopping list.

Final Thoughts

Replacing a faucet is a fairly easy DIY project that can take about an hour to complete. In order to make sure it doesn’t end up taking a lot longer, it’s important to make sure the new faucet requires the same number of mounting holes and that all the supplies that aren’t included with the new faucet are on hand when beginning the installation.

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.

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.

Is Rust or Mineral BuildupAround Your Kitchen Sink Faucet?

Rust can indicate the wearing down of the faucet from the inside out. Signs of internal rusting and corrosion in your faucet may look like water taking more than a couple seconds to run or the handles sticking and cracking upon trying to turn them.

If your sink processes hard water, the mineral buildup will develop gradually and will start to look like caked-on, dried toothpaste. Though mineral buildup can be removed from the mouth of the faucet with a water/vinegar solution, it can cause problems if it’s not addressed and it spreads.

Both of these issues lead to your kitchen sink faucet to run far less than optimally and wear it down over time. However, once rust and/or mineral buildup work their way into and impact the inner cogs (gasket, filters, etc) and it’s visible on outer parts of the faucet it’s time to replace it.

STEP 2: Position the faucet in the holes

Attaching the faucet to the sink is pretty easy. After the gasket or putty is in place, set the faucet into the proper holes. Position yourself under the sink, and screw on the plastic nut. If you’ve used plumber’s putty you can clear away the excess with a putty knife or use a finger.

Step 7: Hook Up Your Supply Lines

With all your faucet components in place, you can attach your main water supply. If your faucet did not come with supply lines attached, start by attaching your supply lines to the faucet. Adding Teflon tape around the connectors can help reduce the risk of leakage later, so it’s a good idea to use it if you have it. Once the top is connected, go ahead and hook up the supply lines to the water supply.

After this stage, you can turn your water supply back on. First, make sure your faucet is in the off position. Then, slowly twist the supply line knob, taking care to support the water pipe with your other hand. Avoid cranking them all the way open rapidly. Instead, just do a half-turn or so before checking for leaks. Look on both ends of the supply lines, around the base of the faucet, and around the sprayer connections.

Step 1: Turn Off Water and Power

Now that you know a bit about how the whole process works, let’s get started. We already mentioned it in the safety tips section, but it bears repeating: The very first thing you need to do is turn off the water and power down your garbage disposal.

For most sinks, turning off the water is as simple as twisting the water-shutoff valves underneath your sink. They can stick a little, so give them a small wiggle if necessary. However, if your kitchen doesn’t have individual shutoff valves, you may need to turn off the water to your whole house while you install the kitchen faucet. You can do this by going outside to the water main and turning the lever or twisting the large knob.

Once your water is off, turn on the faucet and let it run until water no longer comes out. That ensures your supply lines are mostly empty.

Most faucets come with a standard design mount for a sink or countertop.

They also come with a deck plate if you are replacing a three-hole faucet with a one-hole faucet.

Our new faucet was a countertop single hole mount with a pull-down spout.

And since we were replacing another single hole faucet we didn’t need to use the deck plate.
