Abstract

A washing machine outlet box of the type capable of fitting within a wall and attaching to wall studs within this wall is improved by incorporating during the manufacture of said washing machine outlet box a disc as an integral part of the bottom wall, with the disc located over the future drain opening. The disc is attached to the bottom wall by a breakable or severable ring. After installation of the washing machine outlet box to an appropriate drain pipe, the disc serves as a plug for pressure testing of the drain pipe and further serves as a dam to prevent introduction of foreign material into the drain pipe during construction stages of the wall and the like. Upon completion of pressure testing and after completion of construction, a tab attaching to the disc is lifted upwardly so as to sever the ring attaching the disc to the wall to free the disc to form the drain opening in the bottom wall of the washing machine outlet box.

A washing machine outlet box capable of fitting within a wall and attaching to support members located in said wall, said washing machine outlet box being an integrally formed water impervious plastic cabinet having a top, a back, sides, a front opening and a bottom with said bottom including a bottom drain opening, the improvement which comprises:

said top of said cabinet having a front edge, said front edge of said top extending forwardly and downwardly over said front opening so as to form an acute angle to the plane of said front opening of said cabinet,
the forwardmost portion of said bottom extending forwardly and upwardly over said front opening so as to form a front edge of said bottom, said front edge of said bottom sloping downwardly towards said drain opening and forming an acute angle to the plane of said front opening of said cabinet, said bottom including a vertically extending wall at the rear of said forwardmost portion which defines a channel with said forwardmost portion which slopes downwardly toward said drain opening,
a face plate shaped as a frame whose outside periphery is of a greater dimension than the outside periphery of the front opening of said cabinet and including an opening located in said frame wherein the periphery of said opening is of a smaller dimension than the outside periphery of said front opening of said cabinet, said face plate including a flange located perpendicularly to said frame and extending around said opening in said frame, said flange sized and shaped so as to extend inwardly into said front opening of said cabinet, said face plate fitting against said cabinet with said flange fitting into said front opening so as to position portions of said flange against said front edges of said top and said bottom, said portions of said flange which fit against said front edges of said top and said bottom including a plurality of longitudinally oriented ridges capable of frictionally engaging said front edges of said top and said bottom.
