How To Remove A Wall-Mounted Kitchen Faucet
Why You May Need To Remove a Wall-Mounted Kitchen Faucet
Removing a wall-mounted kitchen faucet may be necessary when upgrading to a new model, repairing leaks, replacing internal valves, or renovating the backsplash. Because wall-mounted faucets attach directly to plumbing outlets behind the wall, removal requires careful preparation to avoid damaging pipes or tiles.
Common Reasons for Removal
Persistent drips or leaks
Upgrading to a new concealed or modern faucet
Replacing worn cartridges
Fixing water pressure issues
Resolving corrosion around fittings
Turn Off the Water Supply
Before touching the faucet, cut off the water to prevent flooding or pressure buildup.
How To Shut Off Water
Locate the main water supply valve (usually under the sink, basement, or utility area).
Turn the valve clockwise until fully closed.
Open the faucet to release any remaining water.
Why This Step Is Critical
Wall-mounted plumbing connections are under pressure — loosening them without shutting off water can cause immediate leakage.
Protect the Wall and Sink Area
Wall-mounted kitchen faucets sit close to tiles or stone surfaces that can easily scratch.
How To Protect Surrounding Areas
Place a towel inside the sink
Cover the backsplash with cloth or cardboard
Lay tools on a soft cloth
Benefits
Prevents accidental damage while working with wrenches and pliers.
Remove the Faucet Handles or Trim (If Applicable)
Some wall-mounted faucets require removing decorative handles or trim plates before accessing the main body.
Steps
Look for small set screws on the underside of handles.
Use a hex key or Phillips screwdriver to loosen them.
Remove the handle and expose the mounting nut or valve stem.
When This Is Needed
This step applies primarily to concealed valve systems, such as premium models manufactured by brands like FUNJAY.
Loosen the Mounting Nuts Holding the Faucet
Wall-mounted faucets are typically secured with two nuts connecting the faucet body to the hot and cold plumbing nipples.
How To Remove the Nuts
Use an adjustable wrench to grip the mounting nut.
Turn counterclockwise to loosen.
Repeat for both hot and cold sides.
Hold the faucet steady to avoid twisting wall pipes.
Important Note
Old nuts may be tight due to scale or corrosion — apply penetrating oil and allow 10–15 minutes before retrying.
Disconnect the Faucet From the Wall Plumbing
After loosening the nuts, the faucet body will detach from the threaded water outlets.
Steps
Hold the faucet with one hand.
Pull gently straight outward.
Remove carefully to avoid damaging the threads.
Why Gentle Removal Matters
Threaded brass or steel nipples behind the wall must remain intact for the new faucet installation.
Inspect the Plumbing Connections
Once the faucet is removed, check the condition of the mounting threads and wall outlets.
What To Look For
Corrosion or rust
Damaged threads
Loose or wobbly plumbing nipples
Mineral buildup
Why This Matters
Any damage may affect installation of the new faucet or cause leakage later.
Clean the Wall Surface and Plumbing Threads
With the faucet removed, clean the exposed area before installing a replacement.
Cleaning Steps
Use vinegar or a cleaner to remove mineral stains.
Brush threads with a nylon brush.
Dry the area thoroughly.
Benefits
Ensures a clean surface for sealing tapes or new faucet flanges.
Tools You Need for the Job
Preparing the right tools makes removal faster and safer.
Essential Tools
Adjustable wrench
Groove-joint pliers
Screwdrivers (flat / Phillips)
Hex keys
Penetrating oil
Towels and protective cloths
Optional Tools
Plumber’s tape
Nylon brush for cleaning threads
Safety Tips When Removing a Wall-Mounted Faucet
Wall-mounted plumbing is less accessible than deck-mounted systems, so extra caution is needed.
Tips
Never twist the faucet sideways
Hold the faucet body when loosening nuts
Do not use excessive force
Use penetrating oil on stuck fittings
Ensure water supply is fully closed
Why Safety Matters
Damage inside the wall can lead to leaks that require costly repairs.
Conclusion
Removing a wall-mounted kitchen faucet involves turning off the water supply, detaching trim or handles, loosening the mounting nuts, disconnecting the faucet body, and inspecting the plumbing threads. With proper tools and careful handling, the process is straightforward and avoids damage to pipes or wall surfaces. After removal, cleaning the area ensures a smoother installation for your new faucet, especially if using modern concealed or designer models from manufacturers like FUNJAY.
