Possible Reasons for Pump Failure



Loose or Faulty Connections

Ensure that all connections from the extension cord to the pump and from the power source to the receptacle in the yard are secure.

Insufficient Power

Check if the circuit breaker or fuse for the outdoor power source is tripped or blown. Also, verify that the gauge of the extension cord is appropriate for the pump's power draw.

Ground Fault Interrupter (GFI)

If the outdoor power source is GFI-protected, it may have tripped due to a ground fault. Reset the GFI and ensure that there are no ground faults in the circuit.

Incompatible Wiring

Check the wiring configuration of the receptacle in the yard. It may be wired incorrectly, such as with reversed polarity, causing the pump to malfunction.

Defective Pump

The pump itself may be faulty or damaged. Disconnect the pump and test it using the extension cord as a power source. If the pump still doesn't work, it may need to be replaced.

Additional Factors to Consider



Interference from Lights on Circuit

Lights on the same circuit can create electrical noise that can interfere with the pump's operation. Try disconnecting the lights and see if the pump starts running.

Outdoor Conditions

Exposure to moisture or extreme temperatures can affect the operation of electrical equipment. Check for any signs of corrosion or damage on the pump, extension cord, or receptacle.

Incorrect Voltage: Ensure that the voltage supplied to the pump is within its rated range. Some pumps require specific voltages to operate correctly. Flag for review
