A typical building normally has two or more shafts, which travel from the lowest level of the building to its terrace. Such shafts are normally used to carry the piping for the wet-riser systems. Hydrant outlets are provided on every floor so that the entire floor area of the building is adequately covered. Outlets are provided in the form of double-outlet landing valves.
