    Why is my CSI Water Filtration System producing poor water quality?
    • K
      khollandAug 20, 2025
      Poor water quality in your CSI Water Filtration System can stem from several causes. Start by ensuring the bypass valve is closed. Also, check for channeling, which may be due to service flow being too slow or high, or media fouling. Insufficient aeration can also be a factor; try programming the valve to draw air more frequently or increasing the minutes in the air draw cycle. Finally, clean the injection assembly and screen.

      If your CSI Water Filtration System is regenerating at the wrong time, it's likely due to the time of day or regeneration time being improperly set, often after a power failure. Reset the time of day and regeneration time programming. Consider installing a 9-volt battery to preserve settings during power outages.

    What to do if my CSI Water Filtration System has a loss of water pressure?
    • A
      Allison SmithAug 26, 2025
      Loss of water pressure in your CSI Water Filtration System can be attributed to a few reasons. Check for scaling or fouling in the inlet pipe, and clean or replace the pipeline, pretreating to prevent recurrence. Also, inspect for fouled media and clean it, pretreating to prevent future fouling. Lastly, ensure the backwash setting is appropriate and increase backwash frequency if needed.

      Ryan JonesAug 30, 2025
      If your CSI Water Filtration System isn't regenerating automatically, there are several potential causes. First, ensure the power supply is connected to a constant power source. An intermittent or dead power source can prevent regeneration. Second, improper control valve programming can be the issue, so try resetting the program settings. Third, a defective power supply may be the root cause, in which case you should replace the power supply. Finally, a defective drive motor can cause this problem, so consider replacing the motor.
