a) In
General. Prohibition. Any pipe, any pipe or plumbing fitting or fixture, any
solder or any flux must be lead free, as defined by subsection (b), if it is
used in the installation or repair of either of the following:
1) Any PWS; or
2) Any plumbing in a residential or
nonresidential facility providing water for human consumption that is connected
to a PWS. This subsection (a) does not apply to leaded joints necessary for the
repair of cast iron pipes.
b) Definition of Lead Free
1) For purposes of this Section, the term
"lead free" means as follows:
A) When used
with respect to solders and flux, refers to solders and flux containing not
more than 0.2 percent lead; and
B)
When used with respect to pipes, pipe fittings, plumbing fittings, and
fixtures, refers to pipes and pipe, pipe fittings, plumbing fittings, and
fixtures containing not more than 0.25 percent lead.
2) The weighted average lead content of a
pipe, pipe fitting, plumbing fitting, or fixture must be calculated by using
the following formula: For each wetted component, the percentage of lead in the
component must be 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. The weighted percentage of
lead of each wetted component must be added together, and the sum of these
weighted percentages will constitute the weighted average lead content of the
product. The lead content of the material used to produce wetted components is
used to determine compliance with subsection (b)(1)(B). For lead content of
materials that is provided as a range, the maximum content of the range must be
used.
