A kitchen faucet is one of the most used fixtures in any home—so when it starts leaking, getting stiff, or looking outdated, it’s often worth replacing. Whether you’re upgrading to a modern pull-down faucet or swapping out an old, corroded one, installing a new faucet can completely refresh your kitchen.
Here’s a professional guide on how to replace a kitchen faucet safely and correctly.
⭐ What You’ll Need
- Adjustable wrench
- Basin wrench
- Plumber’s tape (Teflon tape)
- Bucket or towel
- New faucet (single-hole, 3-hole, or 4-hole setup)
- Silicone sealant (if required)
- Flashlight
⭐ 1. Shut Off the Water Supply
Before starting any faucet replacement:
- Look under the sink for the two shut-off valves (hot and cold).
- Turn them clockwise to close.
- Open the faucet to release pressure and drain leftover water.
- Place a towel or bucket underneath to catch drips.
Pro Tip:
If your valves don’t shut off fully—or if they’re corroded—it’s best to have a professional handle it. Faulty valves can break and cause water damage.
⭐ 2. Disconnect the Water Lines
Using an adjustable wrench:
- Disconnect the hot and cold supply lines from the shut-off valves.
- Disconnect the supply lines from the faucet itself (if they’re not built-in).
You may see some water drip out—this is normal.
If space is tight, a basin wrench will help reach the nuts behind the sink bowl.
⭐ 3. Remove the Old Faucet
From underneath the sink:
- Locate the mounting nuts holding the faucet in place.
- Loosen and remove them using a basin wrench.
- Gently pull the old faucet up and out from the top.
If it’s stuck due to old caulking or mineral buildup, carefully pry it up—avoid scratching the countertop.
⭐ 4. Prep the Sink Area
Before installing the new faucet:
- Clean any old silicone or putty from the sink surface.
- Check your faucet holes (single, 3-hole, or 4-hole).
- If your new faucet includes a deck plate, use it to cover extra holes.
A clean, flat surface ensures a watertight seal.
⭐ 5. Install the New Faucet
Follow the manufacturer’s instructions, but here’s the general process:
- Insert the faucet or deck plate through the mounting holes.
- Apply silicone sealant underneath if required.
- From underneath the sink, tighten the mounting nuts to secure the faucet.
- Make sure the faucet is straight and centered before final tightening.
Pro Tip:
Some faucets come with pre-attached supply lines—these make installation much easier and reduce the chance of leaks.
⭐ 6. Reconnect the Water Lines
- Connect the hot and cold water lines to the matching shut-off valves.
- Wrap threaded connections with plumber’s tape if the manufacturer recommends it.
- Hand-tighten, then snug with a wrench—don’t over-tighten.
If your faucet includes a sprayer hose, make sure it is securely clipped and unobstructed.
⭐ 7. Turn the Water Back On
- Slowly open the hot and cold shut-off valves.
- Turn the faucet on and let the water run for 1–2 minutes.
- Check under the sink for leaks.
- Tighten connections if needed.
⭐ 8. Test All Functions
Make sure:
- Hot and cold water flow properly
- Pressure is normal
- The sprayer extends and retracts smoothly
- There are no drips at any connection
If everything works perfectly, the job is complete!
Should You DIY or Hire a Professional?
Replacing a kitchen faucet is doable for many homeowners—but it can get complicated if:
- Space under the sink is tight

A professional handyperson ensures the faucet is installed securely, without leaks, and up to plumbing standards.
