Abstract
An apparatus for sealing the central opening in a conventional closet flange extending perpendicular to a drain pipe. A generally disk-shaped sealing member is connected to the lower end of a threaded shaft screwed through an intermediate hub in a diametrically extending mounting body. A pair of L-shaped retaining arms are pivotally connected to corresponding ends of the mounting body. Heads on the lower ends of the retaining arms may be inserted through diametrically spaced key-shaped slots in the closet flange and engaged with the underside of the flange. A handle connected to the upper end of the shaft may be turned to screw the shaft downwardly. This firmly presses an elastomeric boot on a convex underside of the sealing member against an inner edge of the central opening in the closet flange. This seals the opening in the closet flange to permit pressure testing of the drain and its associates sewer system.
