Check Valves


The Aquascape Dual Union Check Valve provides a professional pump and plumbing connection inside the skimmer filter system, as well as the Pondless Waterfall vaults. The heavy-duty swing style  check valve flapper maximizes water flow through the valve when open, while preventing the back flow of water  when the pump is shut off or during a power outage. Union connections on both sides of the valve make pump  and filter  maintenance quick and easy without the use of tools. A set of reversible fittings takes the guess work of finding the right pump or filter fitting and allows the extension of valve height for the taller filter applications. Choose from either a 2" Dual union check valve or a 3" CVA check valve.
