      vdavisJul 29, 2025
      If your Redlion Water Pump isn't delivering water, several factors could be at play. First, ensure the pump is completely primed. If the suction lift is too high, relocate the pump closer to the water source. Also, check the foot valve to ensure it is submerged and not obstructed by mud or other debris; clean or replace it if necessary.

      rbarajasAug 10, 2025
      If your Redlion Water Pump loses prime, check for air leaks in the suction line and repair or replace as needed. If the well draws down too far, move the pump closer to the water source. Also, inspect the foot valve and clean or replace it if faulty.

    Why does my Redlion RJS-PREM start and stop too often?
    • J
      Joshua RossAug 15, 2025
      If your Redlion Water Pump starts and stops too often, it could be due to a faulty air volume control, which would require replacement. Alternatively, there might be air leaks in the tank above the water level; check the fittings and consider replacing the tank. Another cause can be incorrect setting on the pressure switch.

    What to do if my Redlion RJS-PREM delivers water, but not at rated capacity?
    • A
      Andrew KeithAug 21, 2025
      If your Redlion Water Pump delivers water but not at its rated capacity, there are several potential causes. Check for leaks in the suction or discharge lines, and clean or replace them as needed. Inspect the foot valve, suction line, impeller, or nozzle for partial blockages and clean as necessary. If the suction lift is greater than recommended, relocate the pump closer to the water source. Ensure the proper gauge wire has been used and verify that the motor is wired for the correct voltage, matching the voltage at the power source.
