Questions and Answers

    Why is there continual high water flow to drain and no product water in my EcoWater Water System?
    • E
      Elizabeth ShawSep 4, 2025
      If your EcoWater Water System has a continual high water flow to the drain but is producing no product water, it could be due to a missing flow restrictor in the red drain tube or its corresponding port. Replace the flow restrictor.

    What to do if the LED indicator light on my EcoWater Water Filtration System faucet isn't working after changing the batteries?
    • N
      Nicholas BernardSep 18, 2025
      If the LED indicator light on your EcoWater faucet isn't working after a battery change, first ensure the batteries are new. If it still doesn't work, the batteries may be installed incorrectly; make sure they are properly oriented.

    Why is there continual high water flow to drain but no product water from my EcoWater Water Filtration System?
    • D
      Derek GibbsSep 16, 2025
      If your EcoWater system has a continuous high water flow to the drain but isn't producing any product water, it's likely due to a missing flow restrictor in the red drain tube or its corresponding port. Replace the flow restrictor to resolve this issue.

    Why is water leaking from the air gap hole of my EcoWater Water Filtration System faucet?
    • B
      Bradley AyersSep 14, 2025
      Water leaking from the air gap hole of your EcoWater faucet usually means the drain side of the faucet air gap (3/8" tubing) is plugged, restricted, or incorrectly connected to the drain point. Inspect the tubing and eliminate any restrictions or plugs. Refer to the installation instructions for proper drain connection.

    Why is the LED flashing red on my EcoWater Water Filtration System?
    • A
      Amanda EwingSep 12, 2025
      A flashing red LED on your EcoWater system, indicating high total dissolved solids (TDS), can be caused by a water supply that doesn't meet the system's specifications. Increase water pressure or precondition the water to meet requirements. It could also mean the RO membrane cartridge is expended. In this case, replace the prefilter, postfilter, and RO membrane cartridges, flow control, and screen.

    What to do if my EcoWater Water Filtration System has a bad taste or odor?
    • M
      Michael StewartSep 12, 2025
      If your EcoWater system's water has an unusual taste or odor, it could be due to several factors. The post filter might be expended, so try replacing it. If the issue continues, replace the prefilter cartridge and RO membrane cartridge. Another possible cause is contamination in the product water storage; in that case, use sanitizing procedures and replace the post filter cartridge.

    What to do if my EcoWater Water Filtration System makes water too slowly?
    • K
      Kristin JordanSep 9, 2025
      If your EcoWater RO system is producing water slower than usual, it could be due to a few reasons. First, ensure the water supply to the system meets the required specifications by increasing water pressure or preconditioning the water as needed. Another cause may be that the prefilter or RO membrane cartridges are clogged with sediments. Replace the prefilter cartridge; if the rate doesn't improve, replace the postfilter and RO membrane cartridges. Lastly, check and clean the Flow Control Insert, as it may be plugged.

    Why does my EcoWater Water Filtration System have a chlorine taste?
    • J
      Joe RichSep 7, 2025
      A chlorine taste or odor in your EcoWater RO system's product water is often due to either excessive chlorine in your water supply, which can damage the RO membrane, or the prefilter no longer effectively reducing chlorine. If your water supply contains more than 2.0 ppm of chlorine, you'll need additional pre-filtering. Replace the prefilter, post filter, and RO membrane cartridges.

    What causes continual water flow to the drain in my EcoWater Water Filtration System?
    • M
      meyersbrianAug 20, 2025
      Continuous water flow to the drain in your EcoWater system can be caused by a check valve or automatic shutoff assembly that is plugged, restricted, or has worn parts. You'll need to clean, repair, or replace these components as necessary.
