    Why is the water quality poor with my RainSoft Water Filtration System?

      Robert AllenSep 12, 2025
      If you're experiencing poor water quality with your RainSoft Water Filtration System, there could be several reasons: * The raw water source may have changed, requiring a new water analysis from your RainSoft dealer. * The bypass valve might be open, so ensure it is closed. * The power supply could be disconnected, in which case you should plug it in.

    Why is my RainSoft Water Dispenser system failing to use salt?
    • C
      Cassandra ArnoldSep 12, 2025
      If your RainSoft Water Dispenser system fails to use salt, the drain line might be plugged or restricted, so check the water flow to the drain and look for crimps in the drain line, and call your RainSoft Dealer for service. The injector might be plugged, requiring service from your RainSoft Dealer. Low inlet pressure could also be the culprit, so call your RainSoft Dealer to increase the inlet pressure to a minimum of 20 psi. Also, there might be no water in the brine tank, so call your RainSoft Dealer for service.

      If you're experiencing excessive water in the brine tank or salty water with your RainSoft Water Dispenser, the drain line might be plugged or restricted, so check the water flow to the drain and inspect for crimps in the drain line, and call your RainSoft Dealer for service. The brine valve could be dirty, requiring service from your RainSoft Dealer. Low inlet pressure could also be a factor, so call your RainSoft Dealer for assistance. Additionally, the injector might be plugged, requiring service from your RainSoft Dealer.

    How to troubleshoot loss of water pressure in a RainSoft Water Dispenser?
    • J
      Jeremy CummingsSep 16, 2025
      If you're experiencing a loss of water pressure with your RainSoft Water Dispenser, it could be due to low pressure to the unit. Bypass the system; if the problem persists, it's not related to the RainSoft product. Check your water distribution system. If the issue resolves after bypass, call your RainSoft Dealer for service.
