What to do if my Little Giant 5.5-ASPA Water Pump does not turn on?
- A
  Andrea WilliamsJul 28, 2025
  If your Little Giant Water Pump doesn't turn on, there might be several reasons: * It might not be plugged in, so ensure it is properly connected. * The circuit breaker could be off, or the fuse might be removed; in this case, turn on the circuit breaker or replace the fuse. * There could be an accumulation of trash on the float, so you should clean it. * The float path could be obstructed, so check and clear any obstructions. * The switch might be defective, requiring replacement. * The motor itself could be defective, which would mean replacing the entire pump.

  Thomas RobertsonAug 2, 2025
  If your Little Giant Water Pump runs but doesn't discharge liquid, consider these possibilities: * The check valve might be installed backward. Ensure the flow indicating arrow on the check valve body is correctly oriented. * The check valve could be stuck or plugged; remove it and inspect its operation. * The lift might be too high for the pump's capacity; check the rated pump performance. * The inlet to the impeller could be plugged; pull the pump and clean it. * The pump might be air locked; remove the pump and clean the air bleed hole.

Why does my Little Giant Water Pump cycle continuously?
- B
  Breanna HernandezAug 12, 2025
  If your Little Giant Water Pump cycles continuously, consider these potential causes: * There might be no check valve in a long discharge pipe, allowing liquid to drain back into the basin; install a check valve in the discharge line. * The check valve could be leaking; inspect it for correct operation. * The basin might be too small for the inflow; consider installing a larger basin.

  If your Little Giant Water Pump isn't delivering its rated capacity, here are some things to check: * The lift might be too high for the pump; verify the rated pump performance. * The rotation could be incorrect; switch any two of the line wires. * The voltage might be low, causing the speed to be too slow; ensure the supply voltage matches the nameplate rating. * The impeller or discharge pipe could be clogged; pull the pump and clean it, and check the pipe for scale or corrosion. * The impeller might be worn due to abrasives, requiring pump replacement.
