- Wear appropriate personal protective equipment (PPE) such as gloves and safety goggles to protect against potential hazards.
- Use tools and equipment in accordance with manufacturer instructions and safety guidelines.
- Work in a well-ventilated area to avoid exposure to harmful fumes from adhesives or sealants.
- Keep the work area clean and free from any obstacles to prevent accidents or tripping hazards.
3. Tools and Materials Required:
- Shower mixer unit
- Adjustable wrench
- Screwdriver set
- Pipe cutter
- PTFE tape
- Silicone sealant
- Spirit level
- Measuring tape
4. Procedure:
Step 1: Preparation
1.1. Measure and mark the desired position for the shower mixer on the wall, ensuring it is at a suitable height for comfortable use.
1.2. Check the wall surface for any irregularities or damage that may affect the installation process.
Step 2: Installing Pipes
2.1. Cut the existing water supply pipes to the appropriate length using a pipe cutter.
2.2. Clean the pipe ends to remove any debris or burrs.
2.3. Apply PTFE tape to the threaded ends of the pipes to create a watertight seal.
2.4. Connect the pipes to the inlet ports of the shower mixer unit, ensuring they are securely tightened using an adjustable wrench.
Step 3: Mounting the Mixer Unit
3.1. Position the shower mixer unit on the wall at the marked location.
3.2. Use a spirit level to ensure the unit is horizontally aligned.

4.2. Use PTFE tape to seal the threaded connection and prevent any water leaks.
Step 5: Sealing and Finishing
5.1. Apply a bead of silicone sealant around the edges of the mixer unit to create a waterproof seal.
5.2. Smooth the sealant with a damp cloth or finger to ensure a neat finish.
5.3. Allow sufficient time for the sealant to cure before turning on the water supply.
Step 6: Testing
6.1. Turn on the water supply and test the shower mixer for proper functionality.
6.2. Check for any leaks or irregularities in water flow and temperature.
6.3. Adjust the mixer settings as necessary to achieve the desired water temperature and pressure.
5. Compliance with Standards:
Ensure that the installation of the shower mixer complies with relevant industry standards and guidelines, such as:
- National Plumbing Code
- Manufacturer’s Installation Instructions
