12" PVC DWV Fabricated Backwater Valve (S x S)

PVC Backwater Valves are designed to help prevent fluids from re-entering drainage systems, should backflow occur. Unidirectional flow through the valve is created by a flap that freely opens during outflow, and is trapped closed if backflow occurs.

  • Both ends fit over Schedule 40 DWV pipe
