Section XII-335 - Distribution [formerly paragraph 12:012-1]A. All potable water distribution systems shall be designed, constructed, and maintained so as to prevent leakage of water due to defective materials, improper jointing, corrosion, settling, impacts, freezing, or other causes. Valves and blow-offs shall be provided so that necessary repairs can be made with a minimum interruption of service.B.1. Any solder or flux which is used in the installation or repair of any public water system or any plumbing in a residential or nonresidential facility providing water for human consumption shall be lead free (i.e., shall not contain more than 0.2 percent lead). Any pipe, pipe fitting, plumbing fitting, fixture, and any other appurtenance which is used in the installation or repair of any public water system or any plumbing in a residential or nonresidential facility providing water for human consumption shall be lead free (i.e., shall not contain more than a weighted average of 0.25 percent lead when used with respect to the wetted surfaces of pipes, pipe fittings, plumbing fittings, fixtures, and any other appurtenances).2. Exception. The lead free requirement of Paragraph B.1 above shall not apply to: a. leaded joints necessary for the repair of existing cast iron pipes;b. pipes, pipe fittings, plumbing fittings, fixtures and any other appurtenances, including backflow preventers, that are used exclusively for nonpotable services such as manufacturing, industrial processing, irrigation, outdoor watering, or any other uses where the water is not anticipated to be used for human consumption; or,c. toilets, bidets, urinals, fill valves, flushometer valves, tub fillers, shower valves, service saddles, or water distribution main gate valves that are 2 inches in diameter or larger.C.1. Water Piping Quality. All potable water pipes, pipe related products and materials that join or seal pipes and pipe related products shall be evaluated and listed as conforming with a national consensus product (or material) standard, ANSI/NSF Standard 61, and NSF/ANSI 372.

[formerly paragraph 12:012-3] Where pumps are used to draw water from a water supply distribution system or are placed in a system to increase the line pressure, provision must be made to limit the pressure on the suction side of the pump to not less than 20 psi (pounds per square inch) gauge. Where the use of automatic pressure cut-offs is not possible, such pumps must draw water from a tank, supplied with water from a water distribution system through an air gap that complies with ASME Standard A112.1.2-2004.E. [formerly paragraph 12:012-4] All public water supplies shall be operated and maintained to provide a minimum positive pressure of 20 psi gauge at all service connections at all times.La. Admin.
