A system and method for servicing restrooms on the upper floors of a high rise building. The system is comprised of sections of hoses that are interconnected by valves, each valve configured to provide a user with the ability to selectively shut off the flow of material in a vertical or horizontal direction. These vacuum hoses are then connected to a liquid cooled pump, which is connected to a vacuum tank. The system operates by selectively opening and closing the vertical and horizontal valves to focus vacuum force in areas to be cleaned and prevent vacuum in non-desired areas.
