Step-by-Step Guide
Turn Off the Water Supply
Locate the Shut-Off Valve: Turn off the water supply to the bathroom. If your home does not have a separate shut-off valve for the bathroom, you will need to turn off the main water supply.
Drain the Faucets: Open the tub faucet to drain any remaining water and relieve pressure in the pipes.
Remove the Old Faucet
Diverter Spout
Locate the Set Screw: Look underneath the spout for a small set screw. It may be hidden under a decorative cap.
Remove the Set Screw: Use a hex key to loosen and remove the set screw.
Slide Off the Spout: Gently pull the spout away from the wall. If it’s stuck, use a utility knife to cut through any caulk or sealant.
Threaded Spout
Unscrew the Spout: Turn the spout counterclockwise to unscrew it from the pipe. You may need an adjustable wrench for extra leverage.
Remove the Spout: Once unscrewed, pull the spout away from the wall.
Prepare the Pipe
Clean the Threads: If your spout was threaded, clean the pipe threads with a brush to remove any debris or old plumber’s tape.
Apply Plumber’s Tape: Wrap plumber’s tape around the pipe threads to ensure a tight seal for the new spout.
Install the New Faucet
Diverter Spout Installation
Slide On the New Spout: Align the new spout with the pipe and slide it onto the pipe.
Tighten the Set Screw: Use a hex key to tighten the set screw securely.
Threaded Spout Installation
Screw on the New Spout: Align the new spout with the pipe threads and turn it clockwise to screw it onto the pipe.
Tighten the Spout: Use an adjustable wrench to ensure the spout is securely tightened.
Check for Leaks
Turn On the Water Supply: Slowly turn on the water supply and check for any leaks around the new faucet.
Inspect for Drips: Open and close the faucet several times to ensure there are no drips or leaks.
Seal the Spout (Optional)
Apply Silicone Caulk: If desired, apply a thin bead of silicone caulk around the base of the spout where it meets the wall. This helps prevent water from seeping behind the wall and causing damage.
Smooth the Caulk: Use a damp finger or a caulking tool to smooth the caulk for a clean finish.
Tips and Troubleshooting
Stuck Spout
If the old spout is stuck and won’t come off, use penetrating oil to loosen it. Apply the oil around the base and let it sit for a few minutes before trying again.
Persistent Leaks
If the new faucet is still leaking, double-check that all connections are tight and properly sealed with plumber’s tape. Ensure that the O-rings and washers are in good condition and properly positioned.
Replacing O-rings and Washers
Sometimes, the leak may be due to worn O-rings or washers. Replace these components in the faucet assembly to fix minor leaks without replacing the entire spout.
