    What causes Pentair PRF 1035CS Water Dispenser to backwash at wrong rate?
    • E
      Eric AllenAug 17, 2025
      If your Pentair Water Dispenser backwashes or rinses at an excessively low or high rate, it may be due to the absence of a drain line flow control. Install a drain line flow control. Alternatively, the drain line may be restricted. Remove any restriction.

      If your Pentair Water Dispenser control will not recharge automatically, make sure the AC adapter or motor is connected to a power source. If it is, and the issue persists, the motor may be defective and require replacement. Also, the meter might be clogged with debris; in this case, remove and clean the meter. Note that the unit will recharge every 7 days regardless.

      If you find flowing or dripping water at the drain or salt line of your Pentair Water Dispenser after a recharge, it could be due to debris preventing the #4 valve disc from closing. Try removing any debris. Alternatively, the #4 valve disc may be worn and require replacement.

      If your Pentair Water Dispenser is not providing conditioned water after a recharge, ensure that there is salt in the salt tank by adding salt to the salt tank. Another possible cause is a plugged injector. In this case, clean the injector and screen.

      If the Pentair Water Dispenser valve will not draw brine, check for a restricted drain line and remove any obstructions. Also, the injector might be plugged, so clean the injector and screen.

      If the flow indicator on your Pentair Water Dispenser control does not display service flow, verify that the bypass valve is not in the bypass position and remove it from bypass. Also, check if the meter cable is dislodged from the valve and fully insert it. Finally, the meter could be clogged with debris, requiring you to remove and clean the meter.
