      Is NSF 372 the same as NSF 61?

      Is NSF 372 the same as NSF 61?

      No! There are two standards that you need to know about, NSF 61 and NSF 372.

      NSF 61

      NSF 61 addresses a range of materials used in plumbing components, not just lead. Certification to this standard shows that a component is unlikely to put any metal into the water.

      NSF 372

      NSF 372, which came into effect in October 2013, applies specifically to lead. Being certified to this standard verifies that a component incorporates less than 0.25 percent lead.

      Typically, plumbing components sold for use in drinking water systems must be certified to one of these standards and will carry appropriate markings.
