Check Valve Dual Union 1.0 – 2" Adapter Series

The Check Valve Dual Union 1.0 – 2" Series is a modular plumbing solution engineered by Aquascape for high-performance pond and water feature systems. Designed for maximum compatibility and ease of maintenance, this system allows you to customize your 2" plumbing line using various interchangeable adapters, including options for Signature Series Skimmers, AquaSurge® pumps, and standard 2" slip fittings.

These components offer true union functionality—meaning they can be removed without cutting pipe—making seasonal servicing, pump replacement, or system upgrades fast and clean. Each piece is crafted from heavy-duty, weather-resistant PVC and includes high-quality O-rings for leak-resistant seals.
