|Publication Date:||25 October 2004|
PURPOSE AND SCOPE.
This UFC provides guidance in the design of plumbing systems, together with the criteria for selecting plumbing materials, fixtures, and equipment and is applicable to all elements of the Department of Defense (DoD) charged with planning military construction. This UFC provides minimum standards to safeguard life or limb, health, property and public welfare by regulating and controlling the design, construction, installation, quality of materials, location, operation, and use of plumbing systems. It is not the intent of this manual to duplicate information contained in the standards cited herein, but to reference them as appropriate (see Appendix A.)
This UFC applies to all service elements and contractors involved in the design and construction of plumbing systems for use in facilities of all branches of service. A plumbing system consists of the water supply distribution system; fixtures, and fixture traps; soil, waste, and vent piping; storm water drainage; acid and industrial waste disposal systems; and special gases (medical and oxygen) systems. The plumbing system extends from connections within a structure to a point 1.5 m (5.0 ft) outside the structure. Additions, alterations, renovations, or repairs to a plumbing system must conform to that required for a new plumbing system without requiring the existing plumbing system to comply with all the requirements of this manual. Do not execute additions, alterations, or repairs that cause an existing plumbing system to become unsafe, hazardous, or overloaded.
