Method Statement for Fixing Basin Mixers

1. Introduction:
Basin mixers are essential fixtures in bathrooms and kitchens, providing control over water flow and temperature. Fixing basin mixers requires careful planning and execution to ensure proper installation and functionality. This method statement outlines the step-by-step procedure for fixing basin mixers, including safety steps and adherence to standard guidelines.

2. Safety Precautions:
Before commencing any work, prioritize safety by following these precautions:

• Turn off the water supply to the basin to prevent accidental water flow.
• Wear appropriate personal protective equipment (PPE) such as gloves and safety goggles to prevent injuries.
• Use tools and equipment in accordance with manufacturer instructions and safety guidelines.
• Ensure the work area is well-ventilated to avoid exposure to harmful fumes from adhesives or sealants.
• Keep the work area clean and free from obstacles to minimize the risk of accidents or tripping hazards.

3. Tools and Materials Required:

• Basin mixer unit
• Adjustable wrench
• Screwdriver set
• Pipe wrench
• PTFE tape
• Silicone sealant
• Spirit level
• Measuring tape

4. Procedure:

Step 1: Preparation
1.1. Turn off the water supply to the basin and open the taps to drain any remaining water from the pipes.
1.2. Clear the area around the basin and ensure there is sufficient space to work comfortably.
1.3. Remove any existing fixtures or accessories that may interfere with the installation process.

Step 2: Mounting the Mixer Unit
2.1. Position the basin mixer unit in the desired location on the basin deck or wall, ensuring it is centered and aligned.
2.2. Use a spirit level to check the horizontal and vertical alignment of the mixer unit.
2.3. Mark the fixing points on the basin or wall surface using a pencil.
2.4. Drill holes at the marked positions for the mounting screws or bolts, ensuring they are the appropriate size for a secure fit.
2.5. Insert the screws or bolts through the mounting holes of the mixer unit and tighten them using an adjustable wrench or screwdriver.

Step 3: Connecting Water Supply Pipes
3.1. Connect the flexible hoses or pipes from the water supply to the inlet ports of the basin mixer unit.
3.2. Ensure the connections are tight and secure using an adjustable wrench or pipe wrench.
3.3. Apply PTFE tape to the threaded ends of the pipes to create a watertight seal and prevent leaks.

Step 4: Sealing and Finishing
4.1. Apply a bead of silicone sealant around the base of the mixer unit to create a waterproof seal and prevent water from seeping into the wall or basin.
4.2. Smooth the sealant with a damp cloth or finger to achieve a neat finish.
4.3. Wipe off any excess sealant and allow sufficient time for it to cure before turning on the water supply.

Step 5: Testing
5.1. Turn on the water supply to the basin and test the mixer unit for proper functionality.
5.2. Check for leaks or drips around the connections and base of the mixer unit.
5.3. Test the mixer handles or levers to ensure they operate smoothly and control water flow and temperature effectively.

5. Compliance with Standards:
Ensure that the installation of the basin mixer complies with relevant industry standards and guidelines, such as:

• National Plumbing Code
• Manufacturer’s Installation Instructions
• Health and Safety Regulations

6. Conclusion:
Fixing basin mixers requires attention to detail and adherence to safety standards to ensure a successful installation. By following this method statement, you can achieve a professional installation that meets functional requirements and safety guidelines. Regular maintenance and inspection are recommended to prolong the lifespan of the basin mixer and ensure continued performance.
