Beyond Lead and Copper: Understanding NSF/ANSI 383 for Safer Drinking Water

When we think about drinking water safety, lead pipes and copper corrosion often come to mind. However, a significant source of potential contamination lies in the non-metallic materials used throughout plumbing systems: gaskets, O-rings, seals, lubricants, and coatings.

Compliance with standards like NSF 383 is critical for ensuring that a plumbing system meets local building codes and health safety requirements. nsfs 383
