<p>FLOOR DRAIN WITH WASTE PIPE REDUCTION A wide floor drain which is adapted to fit a narrow waste pipe includes a wide drain body having an upper flange extending radially outwardly from the upper end thereof and disposed generally flush with a floor surface. The drain body includes external threads which secure an upper exterior nut adapted to compressively engage the underside of the floor. A wide lower flange extending radially inwardly from the lower end defines a narrow bore. A tubular coupling member extends through the lower bore, and includes an upper coupling flange which is dimensioned to be disposed directly superjacent to the lower flange of the drain body. The coupling member also includes exterior threads which secure a lower exterior nut adapted to impinge upon the exterior of the lower flange. Packing means are disposed between the coupling flange and the lower body flange, and between the lower body flange and the lower nut, so that the lower nut may compressively seal the coupling member and the drain body at the lower bore opening. The lower end of the coupling member is securable to a narrow waste pipe. A plurality of coupling members may be provided to facilitate connection to waste pipes of differing diameters.</p> |
