A 3 year transition period to support Australia’s path to reducing allowable lead levels in many plumbing products commenced on 1 May 2023.
The Lead Free WaterMark trademark has been registered and WaterMark Notice of Direction 2021/4.2 Certification transition arrangements for lead free plumbing products has been published on the ABCB website.
Clause A5G4 of NCC 2022 Volume Three (Plumbing Code of Australia) specifies that copper alloy plumbing products in contact with drinking water must limit the allowable lead content to a weighted average lead content of not more than 0.25%.
Manufacturers and suppliers of impacted products should contact their WaterMark Conformity Assessment Body to arrange certification to these requirements.
All relevant plumbing products being installed must meet the new requirements by 1 May 2026.
