A method for mounting a coupling in a concrete wall or floor of a building so that the coupling provides a fluid conduit which comprises: (a) providing an integral plastic coupling for plastic pipe and adapted to be mounted in a cored or drilled hole in a concrete floor or wall defined by spaced apart planar surfaces which comprises a tube with opposed openings having spaced apart inner and outer cylindrical surfaces around a central longitudinal axis of the tube, wherein the inner surface has a first diameter equal to outside diameter of standard plastic pipe and wherein the outer surface has a second diameter slightly smaller than a cored or drilled hole in the wall or floor to fit in an interference fit, a flange around one of the openings in the tube adapted to be secured by an adhesive to one of the spaced apart planar surfaces of the floor or wall; (b) drilling or coring the hole in the concrete floor or wall; and (c) press fitting the coupling into the hole in the wall or floor with an adhesive as a bead at a junction between the outer cylindrical surface of the tube and the flange so as to secure the coupling to the one surface of the wall or floor.
