Questions and Answers

    Why does my Hague WaterMax H3500 Water System water taste bad?
    • C
      christina04Aug 25, 2025
      If your Hague Water System's water tastes bad, it could be due to several reasons. There might be an increase in product TDS, or the Carbon Post-Filter could be exhausted, requiring replacement. The tank and appliance might be contaminated, in which case you should replace the Pre- and Post-Filter and sanitize the tank and appliance. The tank itself might be contaminated, so sanitize it. A tank diaphragm failure could also be the cause, requiring you to replace the tank and postfilter cartridges. Alternatively, the Carbon Post-Filter cartridge might not have been flushed completely, so flush one or two tanks of product water through the Post-Filter.

    How to fix low flow rate from Hague WaterMax H3500 spigot?
    • C
      Courtney StrongAug 26, 2025
      Low flow rate from the spigot in your Hague Water System can be caused by low water production. Adjust the air pressure between 5 and 7 psi to resolve the issue if the tank lost air precharge. If the tank diaphragm slipped, replace the tank. A clogged Carbon Post-Filter can also reduce flow, so replace the Carbon Post-Filter cartridge. Ensure the tank valve is fully open, as a partially closed valve can restrict flow.

    Why are my Hague Water System ice cubes cloudy?
    • M
      mccarthylindaAug 28, 2025
      Cloudy ice cubes from your Hague Water System can be due to an increase in product TDS. Dissolved air in the feed water, which concentrates in the product water, can also cause this issue. Additionally, certain ice cube shapes trap more dissolved air, with smaller, rounded cubes appearing cloudier. To mitigate this, change the ice cube mold shape, make cubes manually if using an automatic ice maker, and let the water sit to release dissolved air before freezing.

    What to do if Hague Water System filter leaks from housing?
    • C
      Christopher HillAug 30, 2025
      If the Pre- or Post-Filter leaks from the housing in your Hague Water System, it may be due to a deformed or stretched O-Ring, or the housing not being tight enough. Try replacing the O-Ring and cleaning the seating surface, or tightening the housing.

    How to fix plugged flow control in Hague WaterMax H3500 Water System?
    • M
      Matthew CurrySep 1, 2025
      If the flow/pressure control in your Hague Water System is plugged, it is likely due to dirt or debris plugging the flow restrictor tube. The solution is to replace the flow restrictor/pressure control.

    How to resolve Hague WaterMax H3500 air gap overflows?
    • W
      William WeberSep 3, 2025
      If the air gap in your Hague Water System overflows, it's likely due to debris lodged in the 3/8-inch tube from the air gap to the drain. To resolve this, disconnect the tube from the drain saddle and clean out the debris.
