Under the Safe Drinking Water Act, what is the maximum lead content allowed for pipe fittings?

Explanation:
Lead content in plumbing parts is tightly controlled to reduce exposure from drinking water. Historically, pipe fittings could contain up to 8% lead by weight on the wetted surfaces. This reflected older brass alloys used for fittings before stricter federal limits were enacted. In 2014, amendments tightened the standard, lowering the allowable lead on wetted surfaces to 0.25% for pipes, fittings, and fixtures (with solder and flux limited to 0.2%). The question reflects the older standard, so 8.0% is the correct reference. If you’re studying current rules, the present limit is 0.25% for pipe and fittings.
