Possible problems and steps to take.

  1. Elevated flow – Pump is trying to process more than it’s designed for. Elevated flows can be due to use of hot tubs, sump pumps and or ground water infiltration.
  2. Breather or vent plugged – Inspect breather and vent, as even partial plugging will activate the alarm.
  3. Leaking Sensing line – Remove pump from tank and make sure sensing bells are tight. Check for cracks and leaking.
  4. Worn Stator or line obstruction – Check amps. Line blockage can cause higher amperage. Worn stator often results in low amperage readings.
  5. Buried wire problem – Inspect the buried wiring for breaks and shorting. Check for wire damage between each pair of leads. If a short is present, replace the wire.
