18 AAC 80.500 - Use of lead prohibited

Current through April 6, 2022

(a) Except as provided under (b) of this section, an owner may use only lead-free pipes, pipe fittings, plumbing fittings, fixtures, solder, or flux in the installation or repair of
(1) a public water system; or
(2) plumbing in a residential or nonresidential facility that
(A) provides water for human consumption; and
(B) is connected to a public water system.
(b) The requirements set out in (a) of this section do not apply
(1) to leaded joints necessary to repair cast iron pipes;
(2) if pipes, pipe fittings, plumbing fittings, or fixtures, including backflow preventers, are used exclusively with nonpotable services; for purposes of this paragraph, nonpotable surfaces include manufacturing, industrial processing, irrigation, outdoor watering, and other uses where the water is not anticipated to be used for human consumption; or
(3) to toilets, bidets, urinals, fill valves, flushometer valves, tub fillers, shower valves, fire hydrants, service saddles, or water distribution main gate valves that are two inches in diameter or larger.
(c) For purposes of (a) in this section,
(1) solder and flux is lead-free if it contains not more than 0.2 percent lead;
(2) pipes, pipe fittings, plumbing fittings, and fixtures are lead-free if the maximum lead content in the pipes, pipe fittings, plumbing fittings, and fixtures is not more than a weighted average of 0.25 percent lead with respect to the wetted surfaces of the pipes, pipe fittings, plumbing fittings, and fixtures; the weighted average lead content of a pipe, pipe fitting, plumbing fitting, or fixture must be calculated using the following formula:
(A) for each wetted component, the percentage of lead in the component is multiplied by the ratio of the wetted surface area of that component to the total wetted surface area of the entire product to arrive at the weighted percentage of lead of the component;
(B) the weighted percentage of lead of each wetted component is added together, and the sum of the weighted percentages constitutes the weighted average lead content of the product;
(C) the lead content of the material used to produce wetted components will be used to determine compliance with this paragraph;
(D) for lead content of materials that are provided as a range, the maximum content of the range will be used.
(d) In (a) and (c) of this section, "fixture" includes a backflow preventer in contact with water intended for human consumption.
