Additional information

Material HDPE


LecoTech Flap Gate is made of exceptionally strong & tough High Density Polyethylene (HDPE) Pipe and Sheet. A small differential pressure on the back of the gate causes it to open automatically to allow discharge through levees, sewer lines or drainage conduits. When water on the face side of the gate rises above water on the back side, the gate closes automatically to prevent backflow. Flap gates are equipped with flat-back seats for attaching to wall thimbles, headwalls, and existing pipe flanges. The seat or frame of the flap gate is attached to a wall or pipe flange and forms the opening through which water passes.
