Aquascape Dual Union 3" Check Valve

The Dual Union 3″ Check Valve effectively prevents backflow in ponds and water features while providing a professional pump and plumbing connection inside filters and waterfall vaults. The heavy-duty check valve flapper is built to last and maximizes water flow through the valve when open while preventing the backflow 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.

Features:

• Connects the pump to water feature plumbing
• Prevents water backflow when the pump is not operating
• Dual-union, tool-free design makes maintenance quick and easy
• Heavy-duty swing-style check valve flapper
