    Why is the conductivity/TDS too high in my BWT bestaqua 22 HQ Water Filtration Systems?
    • B
      Brittany AvilaAug 7, 2025
      The conductivity might be too high in your BWT water filtration system due to several reasons: the preset alarm limit has been exceeded, fluctuating feed water quality, high water temperatures, or defective RO membranes. You can check the alarm limit value. If water bleeding was activated either increase the limit value of conductivity or shut down the blending. Also, check the pre-treatment of the feed water and consider replacing the RO membranes.
