      Hello, thank you for your time and comment. The suggested maintenance is periodic. There are tasks that should be performed monthly, but what should not be left undone is every 6 months, and even more so, the one that is done every year.

      For Both Tank & Tankless Water Heaters
      1. Check Pressure Relief Valve:

      Frequency: Once a year
      Why: Ensures the valve functions properly to prevent excessive pressure buildup.
      2. Inspect for Leaks or Corrosion:

      Frequency: Every 6 months
      Why: Early detection prevents major water damage and repairs.
      For Tank Water Heaters
      3. Flush the Tank:

      Frequency: Once a year (more often if you have hard water)
      Why: Removes sediment buildup, which can reduce efficiency and damage the tank.
      4. Check the Anode Rod:

      Frequency: Every 1-2 years
      Why: The anode rod prevents tank corrosion. Replace if more than 50% worn.
      5. Adjust Temperature Setting:

      Frequency: Check every 6 months
      Why: Ensures optimal temperature (120°F/49°C is recommended for most homes).
      For Tankless Water Heaters
      6. Descale/Flush the Unit:

      Frequency: Once a year (may need more often in hard water areas)
      Why: Prevents mineral buildup that can clog the heat exchanger.
      7. Clean Air & Water Filters:

      Frequency: Every 6-12 months
      Why: Keeps the system running smoothly and efficiently.
      Tip: Always refer to your manufacturer’s manual for model-specific recommendations. Regular maintenance by a professional is also recommended annually.
