      Mary GarciaJul 28, 2025
      If your Goulds Water Pump delivers water but doesn't shut off, it could be due to a plugged or incorrectly adjusted pressure switch. In this case, you should clean and adjust the pressure switch. Another potential cause is a defective suction check or foot valve, which would require replacement.

      Stephen AdamsAug 5, 2025
      If your Goulds Water Pump isn't running, there are several potential reasons. First, the motor thermal protector may have tripped; try resetting it. Second, check for an open circuit breaker or a blown fuse and replace them if necessary. Finally, the motor itself might be defective, requiring replacement.

    What to do if my Goulds J5 cycles excessively?

      David WoodAug 12, 2025
      If your Goulds Water Pump cycles excessively, it could be due to a water-logged pressure tank. Try draining and recharging the pressure tank. Another cause might be the pump being farther than 5 feet from the tank; move the pump closer. High friction loss valves between the pump and tank may also be the reason; replace them with fully open gate valves to reduce friction loss.

    How to fix little or no liquid delivered by Goulds J5 Water Pump?
    • G
      Gregory RogersSep 12, 2025
      If your Goulds Water Pump delivers little or no liquid, it could be due to several reasons. First, the pump might not be primed, the suction pipe submergence may be inadequate, or there could be an air leak in the suction pipe. Prime the pump and ensure the suction pipe is correctly submerged and free of leaks. Second, the discharge or suction may be plugged, or a valve may be closed; clear any blockages and ensure valves are open. Finally, the suction lift or suction losses may be excessive; reduce suction lift and minimize losses.
