Little Giant VCMA-15UL Condensate Removal Pump 65 GPH, 1/2‑Gal Reservoir, Automatic Vertical Float (115V)

The Little Giant VCMA-15UL is an automatic condensate removal pump that handles up to 65 gallons per hour with a 1/2-gallon reservoir for HVAC, dehumidifiers, and refrigeration systems.

This compact, vertical-type condensate pump is built for routine drainage tasks where gravity removal isn’t practical. Its 1/50 horsepower motor and stainless-steel shaft deliver steady performance for air conditioners, high-efficiency furnaces, condensing boilers, and standalone dehumidifiers. The unit ships with a barbed discharge adapter and integrated check valve, and includes thermal overload protection and CSA certification for U.S. and Canadian standards.

How does the VCMA-15UL remove condensate from my system?

The pump senses liquid in its 1/2-gallon ABS tank and activates a vertical float switch to clear accumulated condensate through the discharge line. Its built-in check valve prevents backflow, so drained liquid won’t return to the tank when the pump is idle.

• Automatic vertical float switch for compact footprint
• 3/8" O.D. barbed discharge adapter with built-in check valve
• 1/2-gallon reservoir that triggers pump cycles
• Three 1-1/8" inlet openings to accept multiple sources

What performance and electrical specs should I expect?

Powered by a 1/50 HP, 115-volt motor, the VCMA-15UL is rated to pump up to 65 gallons per hour at 1 foot of lift and will shut off around 15 feet of head. The motor is fan-cooled, draws about 1 amp, and includes thermal overload protection for reliable operation under normal conditions.

• 65 GPH at 1' lift; shut-off near 15' head
• 115 V, 1.0 A, 60 W motor with thermal overload protection
• Maximum water temperature up to 140°F (60°C)
• Maximum pressure around 6.5 PSI

What materials and durability features does this pump offer?

The pump uses corrosion-resistant components to withstand regular condensate exposure. The tank, motor cover, and volute are molded from ABS, while the motor shaft is stainless steel — a combination that balances durability and cost-effectiveness for residential and light commercial use.

• ABS tank and volute resist common condensate corrosion
• Stainless-steel motor shaft for corrosion resistance
• Fan-cooled motor with CSA certification for U.S./Canada
• Designed for water temperatures up to 140°F

How do I install and maintain the VCMA-15UL safely?

Installation is straightforward but requires a few simple checks. Remove the protective cardboard insert shipped inside the tank before powering up, route discharge tubing without kinks, and periodically inspect tubing and the check valve to prevent clogs or backups.

• Remove the included cardboard insert labeled "REMOVE" before use
• Use 3/8" O.D. tubing on the barbed discharge adapter
• Check tubing and fittings for kinks or obstructions regularly
• Unit does not include an overflow detection switch; consider external alarm if required

Who is this pump for? The Little Giant VCMA-15UL is suited to homeowners, HVAC technicians, and small-business operators who need a compact, dependable condensate pump for air conditioners, dehumidifiers, high-efficiency furnaces, and condensing boilers. Choose this model when you need a space-saving vertical switch design, straightforward installation, and certified electrical protection — while remembering it does not include an overflow detection switch, so additional overflow monitoring may be required in sensitive installations.
