ABSTRACT:
The present invention relates to a basement sewer backflow control valve with adapter. A valve such as a ball valve is positioned a sewer line under the floor of a basement with an adapter extending vertically through the basement floor providing a means for opening and closing the valve as needed to ensure flood waters do not backflow into the basement during flooding. The valve and adapter may also be utilized in combination with an in-line check valve. The adapter provides a flush surface with the basement floor.
