ABSTRACT:
An in-wall central vacuuming system has a central receptacle and a vacuum pump for drawing dirt and dust into a network of piping and into the receptacle. The system includes a series of ports strategically located around an interior environment of a residential or commercial building. The series of ports permit a flexible tubular hose to be connected thereto. Each port includes an interior wall mounting plate positioned behind the port and has axially aligned circular openings for receiving the flexible tubular hose. An elbow positioned within the wall attaches to a rearwardly extending tubular portion of the mounting frame and attaches to an odd sized first pipe section. A coupler member attaches the odd sized first pipe section to a universally available second pipe section which is used to create a network of piping for the system.
