Why Ace Irrigation System pump does not deliver rated capacity?
- J
  Joy KhanAug 6, 2025
  Several factors could be at play. It might be due to insufficient submergence of the suction pipe; ensure it's at least 3 feet below the water level. Verify that the pump's voltage matches the power supply voltage. Check the valve, suction piping, foot valve, or well point for any issues. The discharge system head might be too great, or the well depth could exceed the pump's capacity. The pump flow might be greater than the well flow capability. Ensure all connections are airtight and that the suction pipe isn't too small; it should be a 1-1/2" pipe.

What to do if Ace Irrigation System pump will not prime?

  If your pump isn't priming, try these steps: Stop the motor, remove the 1-1/2" pipe plug, and fill the case with water. Ensure the pump voltage matches the power supply voltage. Inspect the valve, suction piping, foot valve, or well point. The foot valve might be sitting in sand or mud, stuck shut, or leaking. Check all connections to ensure they are airtight and check for a leaky shaft seal.

Why Ace Irrigation System pump loses prime after starting?
- J
  Jerry WrightAug 25, 2025
  The issue might be caused by several reasons. The suction pipe might not be submerged enough; it needs to be at least 3 feet below the water level. The well depth might exceed the pump's capability, or the pump flow might be greater than the well's flow capability. Make sure that all connections are airtight.
