How To Change Basin Faucet
Replacing a Basin Faucet is a straightforward way to refresh the look and function of your bathroom or wash area. Whether your old faucet is leaking, outdated, or you’re upgrading to a modern design like those from Funjay Sanitary, this guide explains how to change a basin faucet step by step — safely, efficiently, and with professional results.
1. Tools and Materials You Will Need
Before you begin, prepare the following tools and parts:
Adjustable wrench
Screwdrivers (flat and Phillips)
Basin wrench (optional but helpful)
Plumber’s (Teflon) tape
Silicone sealant or plumber’s putty
Towels or bucket
Cleaning cloth or sponge
New basin faucet and hoses (if not pre-attached)
2. Preparation Steps
Turn Off the Water Supply
Locate the shutoff valves under the sink. Turn both hot and cold valves clockwise until fully closed.
If your basin has no local valves, turn off the main water supply for your home.
Relieve Pressure and Drain
Open the faucet to let out any remaining water in the lines. Place a towel or bucket under the sink to catch any drips.
Clear the Workspace
Remove all items from under the basin to give yourself clear access to the plumbing. Lay a towel or mat for comfort if working in a confined space.
3. Remove the Old Faucet
Step 1: Disconnect the Supply Lines
Use an adjustable wrench to loosen the nuts that connect the hot and cold water supply hoses to the shutoff valves.
If the hoses are damaged or corroded, plan to replace them with new flexible stainless steel lines.
Step 2: Remove the Mounting Nuts
Under the sink, locate the mounting nuts that secure the faucet to the basin or countertop.
If space is tight, use a basin wrench for easier access.
Turn the nuts counterclockwise to loosen and remove them.
Step 3: Lift Out the Faucet
Once the mounting nuts are removed, gently lift the faucet assembly up from the top of the basin.
If the base is sealed with silicone or putty, cut around it carefully with a utility knife.
Remove any residue or old sealant from the sink surface.
4. Clean and Prepare the Installation Area
Before installing the new faucet:
Wipe the surface around the mounting holes clean.
Remove mineral deposits, old sealant, and rust.
Check that the holes match the configuration of your new faucet (single-hole or three-hole).
If necessary, cover unused holes with a deck plate (escutcheon) provided with your new faucet.
5. Install the New Basin Faucet
Step 1: Insert the Faucet
Feed the faucet’s hoses and threaded shank(s) through the basin hole(s) from above.
Ensure that the faucet is centered and the base gasket (if included) is properly aligned.
Step 2: Secure the Faucet Underneath
From below the sink:
Thread the mounting nuts or brackets onto the faucet shank(s).
Tighten them evenly to hold the faucet firmly in place.
Use an adjustable or basin wrench for final tightening, but do not overtighten — this can crack ceramic sinks or distort rubber gaskets.
Step 3: Connect the Water Supply Lines
Attach the hot and cold hoses to their corresponding shutoff valves.
Wrap threads with Teflon tape for a watertight seal.
Tighten with a wrench until snug, then check alignment.
6. Test for Leaks and Operation
Turn the water supply valves back on slowly.
Open the faucet handle(s) to flush air from the lines.
Inspect all joints and hoses for leaks.
Tighten slightly if necessary, but avoid excessive force.
Run the water for a few minutes to ensure smooth flow and balanced temperature.
7. Seal the Faucet Base
Once the faucet is secure and leak-free:
Apply a thin bead of silicone sealant around the base where it meets the sink.
Wipe away excess with a damp cloth for a neat finish.
Allow the sealant to cure according to the manufacturer’s instructions (usually 12–24 hours).
8. Tips for a Smooth Installation
| Step | Common Issue | Recommended Solution |
|---|---|---|
| Removing old faucet | Rusted or stuck nuts | Apply penetrating oil and wait 10 minutes |
| Installing new faucet | Misaligned base | Center faucet before tightening |
| Water connection | Cross-threaded hoses | Start connections by hand first |
| Leak after installation | Loose connection | Tighten gently, recheck gasket alignment |
