The manufacturer says this valve is for horizontal, gravity-flow installations only. The modular design allows interchangeable accessories, the valve can be adapted for shallow or deep-bury installations, and it is molded from tough engineered resins.
A backwater valve helps stop sewage from flowing back into the building drain. It is made for 3" or 4" Sch. 40 DWV lines, so confirm the pipe size and local code requirements, including access, before ordering. Brochure, instructions and a specification sheet are linked below.
