Overview
• Installing water purifier systems—be it a point-of-use unit or whole-house set-up—to ensure safe, clean drinking water.
• Skill level: 3 / 5 (basic plumbing and electrical skills required; integration with existing water lines can add complexity).
• Typical duration: 1 day for point-of-use installations; 2 – 3 days for whole-house systems depending on complexity.
Safety First
• Always switch off the main water supply before beginning installation.
• If the purifier uses electricity (e.g. UV or advanced RO systems), ensure proper isolation and RCD protection.
• Use approved fittings and avoid forcing connections to prevent leaks.
• Adhere to manufacturer guidelines and local plumbing codes for safe installation.
• Inspect all connections for proper sealing and secure mounting.
Tools & Materials
Item | Purpose |
|---|---|
Water Purifier Unit | Cleans and filters water for drinking |
Pre-filters & Post-filters | Remove sediments and further improve water quality |
Tubing & Fittings | Connect the purifier to the water supply seamlessly |
Multimeter & Leak Detector | Ensure connections are leak-free and functional |
Step-by-Step
1. Determine your installation type – choose a point-of-use unit for a single tap or a whole-house system for comprehensive filtration.
2. Switch off the main water supply and drain the pipes at the installation point.
3. Remove any existing filters and prepare the area by cleaning the pipe connections.
4. Mount the water purifier unit securely on the wall or under the counter as per manufacturer instructions.
5. Connect the inlet and outlet piping using the appropriate fittings, ensuring all seals are tight.
6. Turn on the water supply gradually, checking for leaks and verifying water flow through the purifier.
7. Test water quality and adjust settings on the purifier if necessary before finalising the installation.
Completion Checks
• The purifier unit runs smoothly with no water leaks at the connections.
• Water flow and pressure are consistent, and the quality meets the expected standards.
• All components are securely fixed and the installation complies with local regulations.
• The final water test confirms the unit is operating at peak performance.
When to Call a Pro Instead
For installations that involve significant alteration to central plumbing, integration with existing electrical systems, or require certification for water quality, it is advisable to engage a qualified plumber or water treatment specialist for professional installation.
