Step-by-Step Guide to Bathroom Faucet Replacement

1. Shut Off the Water Supply

Locate the hot and cold shut-off valves under the sink and turn them clockwise until fully closed. Open the faucet to release any remaining water pressure.

2. Remove the Old Faucet

• Place a towel or bucket underneath to catch water.
• Disconnect the water supply lines with a wrench.
• Unscrew the nuts holding the faucet in place using a basin wrench.
• Lift the old faucet out and clean the sink surface thoroughly.

3. Install the New Faucet Spout

• Insert the new spout into the center hole of the sink.
• From underneath, secure it with the washer and mounting nut.
• Ensure the spout is straight before tightening.

4. Attach the Faucet Handles and Valves

• Insert the hot and cold valves through the side holes.
• Secure them with washers and nuts.
• Connect the valves to the spout using the included fittings or braided hoses.

5. Connect the Supply Lines

• Wrap plumber’s tape on all threaded connections.
• Attach the new (or existing) supply lines from the valves to the shut-off valves.
• Tighten securely, but avoid overtightening which can damage fittings.

6. Install the Drain Assembly

• Remove the old drain and clean the area.
• Apply plumber’s putty or silicone around the drain flange.
• Insert the new drain and tighten the nut from below.
• Attach the pop-up drain rod and test its movement.

7. Test for Leaks
