What requirement must be met by a plumbing fixture in terms of lead presence?

A plumbing fixture must comply with regulations set forth to minimize lead exposure, particularly in items that come into direct contact with drinking water. The correct requirement states that plumbing fixtures must not contain more than 0.25% lead (or 2.5% lead) when viewed as a weighted average of the wetted surfaces.

Selecting the option that states a maximum lead content of 3% aligns with the guideline that limits toxic substances in fixtures to protect public health and safety. This regulation ensures that plumbing systems do not contribute to lead contamination in drinking water, which is well recognized as a health hazard, especially for vulnerable populations like children and pregnant women.

Understanding this regulation is crucial as it enforces not only compliance with health standards but also informs manufacturers and contractors about acceptable materials in the plumbing industry.
