Little Giant 6-CIA 1/3 HP Submersible Sump Pump — 115V, 2760 GPH, Cast Iron, Diaphragm Switch, 10 ft Cord

Overview

The Little Giant 6-CIA is a float-operated, submersible sump pump designed for steady performance in residential basements, crawl spaces, and light commercial pits. With a 1/3 horsepower shaded pole motor, an oil-filled, hermetically sealed design, and an epoxy-coated cast iron housing, this unit is built to handle regular dewatering tasks with reliability. A built-in diaphragm switch provides automatic on/off control based on water level, while the 10-foot cord offers flexible placement for many setups. The system is suitable for fluids up to around 130°F, making it a practical choice for effluent or water transfer in everyday environments.

Key capabilities

• Automatic submersible operation: diaphragm switch activates between 7 and 10 inches of water, and shuts off between 1 and 4 inches, enabling hands-off use in sump systems.
• Durable construction: epoxy-coated cast iron housing with a non-clog vortex impeller and reliable upper/lower bearings.
• Continuous duty motor: 1/3 HP shaded pole motor with thermal overload protection for sustained performance.
• Discharge and power: 1-1/2" FNPT discharge with a 10 ft power cord, supporting versatile installation.
• Performance envelope: up to 2760 GPH at 5' lift and a max shut-off around 18', facilitating larger-volume transfers.
• Operating limits: 140° F max fluid temperature (per spec), CSA-listed for USA and Canada compliance.

Real-world scenarios

• Basements and crawl spaces prone to occasional flooding or high water levels during storms.
• Light commercial pits, utility rooms, or workshops where regular water transfer is needed.
• Situations requiring moving large volumes of water quickly without constant monitoring.

Tips for best results

For reliable operation, ensure the pump remains fully submerged and the discharge path is free of obstructions. Regularly inspect the diaphragm switch, seals, and impeller for debris buildup. The 10-foot cord provides flexibility in placing the pump away from outlets while keeping power cords tidy and out of the water.
