A method of fabricating a backwater valve. A first step involves providing a fitting having at least two flow openings with an inner diameter. A second step involves providing an annular body having a central passage and a valve member movable between a closed position blocking the central passage and an open position. The annular body has an outer diameter adapted for close fitting insertion within the inner diameter of a selected one of the at least two flow openings. A third step involves inserting the annular body into the selected one of the at least two flow openings and securing the annular body in place.
