How To Change Wall Mount Faucet
Replacing a wall-mounted faucet can instantly refresh your bathroom or kitchen’s look while improving functionality and water efficiency. However, since these faucets are connected inside the wall, changing them requires precision and the right approach.
Whether you’re upgrading to a modern FUNJAY wall-mounted faucet or replacing an old leaky one, this guide walks you through every step—covering tools, preparation, removal, installation, and leak testing—to ensure a professional result that lasts.
1. Why Replace a Wall-Mounted Faucet
Over time, even high-quality faucets can show signs of wear. Common reasons for replacement include:
Leaks or drips due to worn-out cartridges or seals.
Outdated design that doesn’t match your new decor.
Low water pressure from mineral buildup.
Corrosion inside fittings caused by hard water.
Upgrade to modern features like thermostatic control or dual handles.
Switching to a FUNJAY wall-mounted faucet not only restores performance but also enhances the overall elegance of your bathroom.
2. Tools and Materials You’ll Need
Before starting, gather the following tools and materials:
| Tool / Material | Purpose |
|---|---|
| Adjustable wrench | Loosens and tightens nuts and fittings |
| Screwdriver set | Removes wall escutcheons or handles |
| Plumber’s tape (Teflon tape) | Seals threaded joints to prevent leaks |
| Silicone sealant | Waterproofs around wall plates |
| Pipe wrench or basin wrench | For larger fittings or concealed joints |
| Bucket and towels | Catch water and protect the area |
| Replacement faucet | Preferably a FUNJAY wall-mounted model for reliable fit and performance |
Having all tools ready saves time and ensures a smooth workflow.
3. Step-by-Step Guide: How To Change a Wall-Mounted Faucet
Step 1: Turn Off the Water Supply
Locate your bathroom’s main shut-off valve or the specific valve serving the faucet. Turn it clockwise to stop the water flow completely.
Next, open the faucet handles to release residual water in the lines. Place a towel or bucket underneath to catch drips.
Step 2: Remove the Old Faucet
Detach the handles or trim plates.
Use a screwdriver or Allen key to remove decorative covers.Unscrew the mounting nuts or fittings.
Use a wrench to loosen connections between the faucet body and wall plumbing.Gently pull out the faucet assembly.
Avoid using excessive force, especially on tiled walls—work slowly to prevent cracking or damaging the wall finish.
If the old faucet is sealed with silicone or grout, cut around the edges carefully using a utility knife.
Step 3: Clean the Wall and Inspect Plumbing
After removing the old faucet, clean away debris, rust, or leftover sealant.
Check the inlet pipes inside the wall for corrosion, leaks, or misalignment.
If pipes are worn, consider replacing them before installing the new faucet—this prevents hidden leaks later.
Step 4: Prepare the New Faucet
Unpack your new FUNJAY wall-mounted faucet and verify that all components (valve body, handles, spout, gaskets, escutcheons) are included.
Wrap Teflon tape around all threaded connections to ensure tight, leak-free joints. Align the hot and cold water inlets (usually 150 mm apart) according to standard international spacing.
Step 5: Install the Faucet Body
Insert the valve body into the wall opening, connecting it to the hot and cold supply lines.
Use a wrench to tighten both sides evenly.
Ensure the faucet is level horizontally using a spirit level before sealing it in place.
Apply silicone sealant around the escutcheons to waterproof the edges against moisture.
For thermostatic or mixer models, check orientation (hot on left, cold on right) before securing.
Step 6: Attach the Handles and Spout
Once the valve body is installed:
Slide the escutcheon plates into position.
Attach the spout and handles as per manufacturer instructions.
Tighten screws or nuts carefully to avoid over-tightening, which may damage internal cartridges.
Step 7: Turn On the Water and Test for Leaks
Slowly reopen the main water valve.
Let water flow through the new faucet for a few minutes to clear air and debris.
Check around all connections and wall joints for any drips or moisture.
If leaks appear, turn off the water and tighten fittings slightly or reapply Teflon tape.
Step 8: Final Adjustments and Cleaning
Once the installation is leak-free:
Wipe away excess silicone or fingerprints.
Polish the faucet surface with a soft cloth.
Adjust the spout direction or aerator angle if necessary.
Your new FUNJAY wall-mounted faucet is now ready to use—offering both precision flow and timeless style.
4. Professional Tips for Smooth Replacement
✔ Use Quality Materials
Always choose solid brass or stainless steel faucets for better durability and corrosion resistance—key features in all FUNJAY products.
✔ Align Perfectly
Double-check level and spacing before final sealing. Even a small misalignment can affect water flow or appearance.
✔ Protect the Wall
Use soft cloths or padding when using tools near tiles to prevent scratches.
