Abstract
Abstract A washing machine connection structure can be manufactured so as to include a box-like cabinet having a front opening, a bottom shaped as a funnel so as to lead to a drain opening forming a part of the bottom, a pipe extension leading from this drain opening and internally extending outlet openings located above the bottom. The cabinet preferably carries means enabling it to be mounted in a wall between support members such as studs. When so mounted pipes may be inserted through the outlet opening and connected to the valves or faucets located within the cabinet. Water connections to a washing machine or the like may be made to such valves and a drain tube or hose from such machine may be inserted directly into the bottom so that waste water flowing through such a tube will flow through the drain opening.
