Under the lead-free plumbing definition, which statement correctly describes the lead content limits?

• A. Solders and flux may not contain more than 2% lead
• B. Pipes must be lead-free
• C. Solders and flux up to 0.2% lead and pipes, pipe fittings, and well pumps up to 8.0% lead
• D. Pipes and fittings may contain up to 0.2% lead

Answer: (C)

The lead-free plumbing definition uses two different limits for different parts. Solders and flux, which are used at joints and can leach into drinking water, are limited to 0.2% lead by weight. Pipes, pipe fittings, and well pumps may contain lead in their alloys up to 8.0% by weight. This distinction reflects how different components interact with water and manufacturing needs, while still setting strict control where water contact is direct. So the correct description is that solders and flux have a 0.2% lead limit, while pipes, pipe fittings, and well pumps may contain up to 8.0% lead.
