Division 22 Plumbing captures the scope of work at a project site that extends from inside the footprint of a building or structure to, generally, a distance of five feet outside the building.  This section will encompass all distribution of city water to the fixtures in a building; the delivery of fuel-oil, natural gas, or propane to corresponding fuel-burning appliances (including laboratory equipment); the delivery of compressed air to pneumatic tools and to pressurized fire protection systems; and the supply of medical gasses.  It will also cover the plumbing required to carry waste products from a building, including sewage and storm water piping and all associated traps and separators.  Plumbing waste products also include dental waste, acid waste, oil wastes, grease waste, and plaster waste.
