This Architectural Drawing is Elevation of water point outlet. Water outlet means a discharge opening through which water is supplied to a fixture, into the atmosphere (except into an open tank that is part of the water supply), to a boiler or heating system, or to any devices or equipment requiring water to operate but that are not part of the plumbing system. The ports are the small holes around the inside of the toilet bowl that feed the water from the tank into the bowl. For more detailing and information download the drawing file.
