Dual Union Check Valve 2.0

The Aquascape Dual Union Check Valve 2.0 effectively prevents backflow in ponds and water features, ensuring a secure connection for pumps and plumbing in pond skimmers and Pondless® Waterfall Vaults. Its robust swing-style check valve flapper is built for durability, enhancing water flow when open and blocking backflow when the pump is off or during power outages. The unique reversible fittings make it easy to align with the appropriate pump or filter; simply rotate the fitting to the desired position. With union connections on both ends, maintaining pumps and filters is quick and requires no tools. This check valve is compatible with various filter sizes, allowing for convenient height adjustments as needed.
