Wall - mount Hot & Cold water mixer install (40 mins)

Wall-mount hot and cold water mixer installations can be a bit more complex than deck-mounted faucets. Here's a breakdown of the process to help you decide if you should tackle it yourself

Suitable for Wall Mount Mixer Installation (if you have):

Strong Plumbing Skills: Understanding concealed tank systems, water pressure requirements, and proper drainage is crucial.

Experience with Wall Fixtures: Experience installing other wall-mounted fixtures (bathroom sinks, cabinets) is helpful.

Advanced Tools: The job usually requires a drill, level, wrench set, pipe cutters (for specific situations), stud finder, and possibly a hammer and chisel (depending
on the installation).

Matching Replacement Mixer (or knowledge of existing model): If replacing an existing mixer, ensure the new model is compatible with your existing carrier frame and uses the same rough-in measurements (distance between the waste outlet and the wall).

Steps Involved in Wall Mount Mixer Installation (General Overview):

Turn Off Water Supply and Empty Tank: Locate the shut-off valve and turn off the water supply completely. If replacing an existing mixer, flush the toilet to empty 
the tank and disconnect the water supply line.

Install or Prepare the Carrier Frame (if applicable): Follow the manufacturer's instructions to secure the carrier frame to the wall studs using appropriate 
fasteners. Ensure proper alignment and height based on the waste outlet and water supply connections. Use a level to ensure the frame is perfectly horizontal.

Connect Water Supply and Drainage: Connect the water supply line to the fill valve on the carrier frame and the mixer unit using flexible hoses, ensuring secure and leak-proof connections (use Teflon tape). Connect the mixer's waste outlet pipe to the drainage system, following the manufacturer's recommendations.

Mount the Mixer Unit: Hang the mixer unit onto the carrier frame, aligning it properly and following the manufacturer's instructions for securing it to the frame.

Install the Controls: Mount the control panel onto the wall and connect it to the mixer unit following the manufacturer's guide.

Leak Testing and Final Touches: Once everything is assembled, turn on the water supply slowly and check for leaks around all connections. Tighten if necessary. 
Install the mixer hose and holder.

Important Considerations for Wall Mount Mixer Installation:

Hidden Leaks: Since the tank is concealed, even small leaks can cause significant damage within the wall. Double-check all connections for leaks during testing. If 
unsure, consider a professional for leak testing with concealed plumbing.

Weight Support: Wall-mounted mixers put stress on the wall. Ensure the carrier frame is securely fastened to studs that can handle the weight of the unit. Use a stud  finder to locate appropriate studs for secure installation.

Following Instructions Precisely: Improper installation can lead to leaks or malfunctions. Follow the manufacturer's instructions meticulously, and consult online resources or video tutorials specific to your mixer model for a visual understanding.

When to Call a Professional Plumber:

Complex Plumbing Systems: If your bathroom has a complex plumbing layout or requires modifications to pipes for the mixer, it's best to call a professional plumber.
Limited Experience or Confidence: Don't hesitate to call a professional if you feel uncomfortable working with concealed plumbing systems and weight-bearing wall installations.

Hidden Damage or Structural Concerns: If you suspect any damage behind the wall where the mixer will be mounted, or have concerns about the structural integrity of the wall (use a hammer and chisel to check for signs of damage cautiously), consult a professional plumber to assess the situation.

Extensive Repairs or Modifications: If the installation involves extensive repairs to your plumbing system or modifications to the wall, calling a professional  
plumber is recommended.
