Installing a new sink faucet can seem hard at first. But with the right steps, you can do it yourself. This guide shows you how to install a Delta or Moen sink faucet. These brands are popular and easy to work with.
What You Will Need
Before you start, gather these tools and supplies:
- New Delta or Moen faucet
- Adjustable wrench
- Basin wrench (optional but helpful)
- Plumber’s tape (Teflon tape)
- Screwdriver
- Bucket or small container
- Cleaning cloth
- Flashlight (if space is dark)
Step 1: Turn Off the Water
First, turn off the water supply. Look under the sink for two valves. One for hot water, one for cold water. Turn both valves clockwise to close them.
If you do not see valves under the sink, turn off the main water supply to your home.
Open the faucet to let any water drain out. This stops water from leaking when you remove the old faucet.
Step 2: Remove the Old Faucet
Place a bucket or container under the sink. This catches any water left in the pipes.
Use a wrench to loosen the nuts under the faucet. These nuts hold the faucet to the sink.
If the nuts are hard to reach, use a basin wrench. It helps reach tight spaces.
Once the nuts are loose, disconnect the water supply lines from the faucet.
Lift the old faucet out from the top of the sink.
Step 3: Clean the Sink Area
Use a cloth to clean around the faucet holes on the sink. Remove old putty or dirt.
Cleaning helps the new faucet fit well and stop leaks.
Step 4: Prepare the New Faucet
Read the instructions that come with your Delta or Moen faucet. Each model may have small differences.
Wrap plumber’s tape around the threads of the faucet’s water inlet pipes. This helps stop leaks.
Check if your faucet has a gasket or rubber ring. If yes, place it on the base of the faucet.
Step 5: Install the New Faucet
From above the sink, place the new faucet into the holes.
Make sure it fits well and is straight.
Under the sink, screw on the mounting nuts to hold the faucet in place.
Use a wrench to tighten the nuts. Do not tighten too much. Too much force can break parts.

Step 6: Connect the Water Supply Lines
Connect the hot and cold water supply lines to the faucet inlets.
Hot water is usually on the left, cold on the right.
Use a wrench to tighten the connections. Again, avoid over-tightening.
Step 7: Turn On the Water and Check for Leaks
Slowly turn on the water supply valves under the sink.
Open the faucet to let water flow. Watch for leaks under the sink.
If you see water dripping, tighten the connections a little more.
Check all the joints and around the base of the faucet.
