EN
This submersible multi-purpose is designed for clear water transfer applications and household water
removal. The pump is for use with water only.
Do NOT use this pump for:
Flammable, combustible, or explosive fluids
Transferring potable water
Effluent or sewage applications
Applications where debris (gravel, sand, etc.), abrasives, or
corrosives are present
For pumping seawater
Sprinkler applications, as this pump does not deliver enough
pressure
Locations classified as hazardous according to the National Electric Code (ANSI/NFPA)
This pump series is available in manual and automatic models. The manual pump can be converted to
operate in automatic mode by installing a separate liquid level control.
The pump motor is equipped with an automatic resetting thermal protector and may restart unexpectedly.
Thermal Protector tripping is an indication of motor overloading or overheating. This can be caused by
application issues such as an obstructed pump impeller, pump running dry, pump air-locked, pump short
cycling, excessively high or low voltage supply, or possibly a pump, motor, bearing, or seal that has
reached the end of its useful life.
Please examine your pump carefully to ensure that no damage occurred during shipment. If damage has
occurred, please contact the place of purchase. They will assist you in replacement or repair, if required.
This product is covered by a Limited Warranty for a period of 12 months from the date of original purchase
by the consumer. For complete warranty information, refer to www.LittleGiant.com

    How to fix a Little Giant Water Pump that does not turn on?

      Christian HerreraJul 29, 2025
      If your Little Giant Water Pump doesn't turn on, here are a few things to check: * Ensure the pump is properly connected to a power source, ideally a dedicated circuit equipped with GFCI. * Verify that the circuit breaker is on, or replace the fuse if it's removed or blown. * If neither of these resolves the issue, the motor may be defective, requiring a pump replacement.

    What to do if Little Giant 5 Series does not deliver rated capacity?
    • J
      jwhiteAug 8, 2025
      If your Little Giant Water Pump isn't delivering its rated capacity, consider the following: 1. Check if the lift is too high for the pump's capabilities by reviewing the rated pump performance. 2. Confirm that the supply voltage matches the nameplate rating, as low voltage can slow the pump's speed. 3. Inspect the impeller and discharge pipe for clogs, cleaning as necessary, and check the pipe for scale or corrosion. 4. Abrasives may have caused impeller wear, in which case you should replace the pump.

    Why Little Giant 5 Series runs but does not discharge liquid?
    • L
      Lisa CunninghamAug 18, 2025
      If your Little Giant Water Pump runs but doesn't discharge liquid, it could be due to a couple of reasons: * The lift might be too high for the pump. Check the rated pump performance to ensure it's within the pump's capabilities. * The inlet to the impeller might be plugged. If so, pull the pump and clean it.
