Abstract
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.
