Condensate Pump Check Valve for Little Giant

Reliable Backflow Protection for Little Giant Condensate Pump​ When it comes to keeping your condensate removal system running smoothly, a high-quality check valve is non-negotiable—and the CV-10 Condensate Check Valve is engineered specifically for Little Giant’s most popular pump series to deliver uncompromising performance.​ This check valve is exclusively tailored for Little Giant VCL-14, VCL-24, VCMA, and VCC Series condensate pumps—no modifications needed, just a perfect fit that restores or enhances your system’s functionality. It solves the common headache of condensate backflow: by blocking reverse water flow, it prevents annoying pump rapid cycling, reduces unnecessary wear and tear on internal components, and significantly extends the lifespan of your valuable pump.​ Crafted for universal compatibility with standard installations, the valve features dual connection ends that match industry-standard setups: a 1/4-inch MNPT male thread on one side (for pumps with 1/4-inch FNPT fittings) and a .430-inch barbed end on the other (seamlessly pairing with 3/8-inch vinyl tubing). Whether you’re installing it in a residential HVAC system, commercial dehumidifier, or heating unit, the compact design (1.72 inches long x 0.72 inches in diameter) fits tight spaces and supports both horizontal and vertical mounting—no special tools or complex adjustments required.​ Durability is built into every detail: the valve body and seat are constructed from rugged acetal (resistant to corrosion and temperature fluctuations), the sealing O-ring is made of flexible nitrile for a leak-proof seal, and the internal one-way ball is crafted from Buna-N for reliable, long-term operation. Even in continuous drainage scenarios, this check valve maintains consistent performance, preventing leaks and ensuring your condensate flows only in the intended direction.​
