Revisions to plumbing standard tighten lead leaching criteria

NSF International, a global public health organization and standards developer, has issued newly published changes to NSF/ANSI/CAN 61 that further restrict the amount of lead that can leach from plumbing products in drinking water. The requirements are significantly more rigorous to reduce lead leaching from endpoint devices that dispense drinking water, as well as from other components.

The revised criteria for certification to the standard will now require a 5 microgram (µg) reduction in the maximum amount of lead leaching for pluming endpoint devices, and from 3 µg to 0.5 µg for other plumbing components (connector hoses, small shut-off valves, etc.). All products will be required to meet the stricter requirements by Jan 1, 2024.
