When a technician is called to repair pressure issues in a geyser (water heater), they typically follow a series of steps to diagnose and fix the problem. Here's a breakdown of the typical work done:

  1. Initial Inspection:

    • Visual Check: The technician will begin by inspecting the geyser for any visible damage, leaks, or corrosion.
    • Pressure Gauge Check: They will use a pressure gauge to measure the water pressure coming into the geyser to see if it matches the manufacturer’s specifications.

  2. Turn Off Power and Water Supply:

    • The technician will turn off the electrical power supply to the geyser (for electric geysers) and the water supply to ensure safety while working.

  3. Check Inlet Valve and Pressure Reducing Valve (PRV):

    • If the geyser is connected to a pressurized water system, the technician will inspect the inlet valve and pressure-reducing valve (PRV) for any blockages or malfunctions.
    • If the PRV is faulty, it may need to be replaced, as it regulates the water pressure going into the geyser.

  4. Flush the Geyser:

    • If there are any sediment or mineral buildups inside the geyser, the technician may flush the geyser. Sediments can accumulate in the tank and reduce water flow or pressure.
    • This step involves draining the tank and flushing it with clean water to remove the debris.

  5. Inspect the Heating Element:

    • In some cases, pressure issues may arise due to a malfunctioning heating element that’s causing the geyser to overheat and affect pressure. The technician may check and clean or replace the heating element if needed.

  6. Check for Leaks:

    • The technician will carefully check for any leaks in the geyser’s water inlet or outlet pipes. Leaks can significantly impact the water pressure and may require sealing or replacing damaged sections of piping.

  7. Test the Pressure Relief Valve:

    • The pressure relief valve (PRV) is another critical component that ensures safe pressure levels inside the geyser. The technician will test it to make sure it's functioning properly and replace it if it is defective.

  8. Inspect Expansion Tank (If applicable):

    • For geysers connected to a closed water system, an expansion tank might be installed to absorb pressure changes. The technician will check this tank for any damage or air pressure issues.

  9. Check Water Supply System:

    • Sometimes, pressure issues can stem from problems outside the geyser, such as low water pressure in the building’s plumbing system. The technician may need to investigate the supply line, including the main water valve, for any blockages or issues with the water flow.

  10. Test the Geyser:

  • After addressing all potential issues, the technician will restore the power and water supply and test the geyser to ensure that the water pressure is now stable and functioning correctly.
  1. Clean and Final Checks:
  • The technician will clean up the work area, check for any loose connections or fittings, and ensure the geyser is operating as expected before leaving.

These steps may vary depending on the specific type of geyser (electric or gas) and the nature of the pressure issue. If the technician identifies a more complex problem, they may recommend replacing certain parts or even the entire geyser if it is beyond repair.
