Dual Union Check Valve 2.0

The Aquascape Dual Union Check Valve 2.0 stops water from flowing backward in ponds and water features. It creates a reliable connection for pumps and plumbing, especially in pond skimmers and Pondless® Waterfall Vaults. The tough swing-style check valve flapper is built to last, ensuring good water flow when open and stopping backflow when the pump is off or during power outages. The clever reversible fittings make connecting to the right pump or filter simple; just turn the fitting as needed. With union connections on both sides, maintaining pumps and filters is fast and needs no tools. This check valve works with different filter sizes and can be easily adjusted in height.
