Backwater Valves

Two types of backwater 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. Used to prevent backflow at the end of sewer lines or overflow from a sanitary sewer pumping station. Listed by UPC and NSF.
