notice shall be given to the consumer. The consumer shall immediately
comply by having the lead based materials removed from the plumbing
system and replaced with lead free materials. If the lead based materials

the component. The weighted percentage of lead of each wetted component
shall be added together, and the sum of these weighted percentages
shall constitute the weighted average lead content of the product.
The lead content of the material used to produce wetted components
shall be used to determine compliance with paragraph (A)(2), above.

content of the range shall be used.
