- Backwater & Terminal Backwater Valves
Two types of valves, in-line and terminal, ensure one-way flow in storm and sanitary sewer lines where backflow could be a problem. Each valve is equipped with a free-hinged flapper that allows unrestricted flow. Valves come with an access lid that can be easily removed for inspection and cleaning. Both the flapper and access lid have leak-free neoprene gaskets.
Features & Benefits
- In-line and/or terminal valves protect against blockage, groundwater infiltration, higher-than-expected flow.
- Standard: CSA/CAN3 B0-M86.
