Tools and Materials Needed‘

Before starting, gather these essentials:
- Adjustable wrench
- Basin wrench
- Plumber’s tape (Teflon tape)
- Bucket or towel
- Silicone sealant or plumber’s putty
- New faucet assembly and supply lines
Step 1: Turn Off the Water Supply
Locate and close the shut-off valves under the sink. Open the faucet to release any remaining water pressure.
Step 2: Remove the Old Faucet
Disconnect the water supply lines using a wrench. Unscrew mounting nuts beneath the sink and lift out the old faucet. Clean the sink surface before proceeding.
Step 3: Position the New Faucet
Insert the new faucet through the mounting holes. Apply a bead of silicone sealant or plumber’s putty around the base to prevent leaks.
Step 4: Secure the Faucet
From underneath the sink, thread and tighten the mounting nuts by hand, then use a basin wrench for final tightening. Ensure the faucet is level before tightening completely.
Step 5: Connect the Water Supply Lines
Attach the hot and cold water lines to the corresponding valves. Use plumber’s tape on threads to ensure a watertight seal. Tighten connections snugly, but avoid over-tightening.
Step 6: Test for Leaks
Turn the water supply back on and slowly open the faucet. Check all connections for leaks and tighten if necessary.
Step 7: Clean and Finish
Wipe away any excess sealant and clean the faucet. Ensure smooth water flow and check temperature balance.
