Sure! Here's a list of the general servicing tasks a technician would typically perform for a water purifier:

General Servicing of a Water Purifier:

  1. Power Off and Safety Checks:

    • Turn off the power supply to the water purifier.
    • Ensure the water inlet and outlet valves are closed properly.

  2. Cleaning of External Parts:

    • Wipe the external surface of the water purifier with a clean cloth.
    • Check for any visible damage or cracks in the body of the purifier.

  3. Pre-Filter Cleaning/Replacement:

    • Inspect the pre-filter and clean it if it's reusable.
    • If the pre-filter is damaged or clogged beyond cleaning, replace it with a new one.

  4. RO Membrane Cleaning/Replacement:

    • Check the RO membrane for any dirt, scaling, or blockage.
    • If required, clean the RO membrane or replace it if it's worn out or damaged.

  5. Carbon Filter Inspection/Cleaning:

    • Inspect the carbon filter for clogging or wear.
    • Clean or replace the carbon filter depending on its condition.

  6. UV Lamp Inspection/Replacement:

    • Check the UV lamp for functionality.
    • If the UV lamp is burnt out or not functioning, replace it with a new one.

  7. Filter Replacement:

    • Inspect and replace the sediment, carbon, and other filters (if applicable) as per the manufacturer's recommendation or if they are clogged or worn out.

  8. Flush Out the System:

    • Flush the water purifier system to clear any residual impurities from the filters.
    • Ensure the purified water flows smoothly.

  9. Check and Clean the Water Tank:

    • Clean the storage tank to remove any sediment buildup or algae.
    • Ensure the tank is sealed properly and free of leaks.

  10. Check the Pressure Pump:

    • Inspect the pressure pump for smooth operation.
    • Clean the pump if necessary and ensure it's functioning optimally.

  11. Check for Leaks:

    • Inspect all hoses, connections, and valves for any water leakage.
    • Tighten or replace faulty parts if leaks are found.

  12. Inspect the Electrical Components:

    • Check the wiring, electrical connections, and the power supply for safety.
    • Test the electrical components like the PCB (Printed Circuit Board) to ensure they are functioning.

  13. Check the TDS (Total Dissolved Solids) Level:

    • Use a TDS meter to check the water quality and ensure that the purification process is effective.

  14. System Testing:

    • Turn the purifier back on and check the flow rate of purified water.
    • Ensure the system is running smoothly with no unusual sounds or leaks.

  15. Customer Demonstration:

    • After the servicing is complete, demonstrate the proper functioning of the water purifier to the customer.
    • Advise the customer on routine maintenance, when to change filters, and any other care tips.

  16. Documentation and Reporting:

    • Record the work done and any parts replaced.
    • Provide the customer with an invoice and a report detailing the servicing.

Optional Tasks (if applicable):

  • Check and clean the water softener (if applicable).
  • Install a new RO membrane if needed.
  • Perform a sanitization process if required, especially for UV-based systems.

This routine servicing ensures the water purifier works efficiently and provides clean, safe drinking water to the user!
