The 2022 edition of the National Construction Code (NCC) will introduce a new limit for the allowable level of lead in plumbing products used for drinking water. From 1 September 2025, copper alloy plumbing products containing more than 0.25% lead will no longer be authorised for installation in a plumbing system used to convey drinking water.
While existing products are safe, health officials recommend that where exposure to lead can be reduced, it should be reduced. During the transition period between 1 September 2022 and 1 September 2025, plumbing practitioners may continue to install existing products as well as those with a reduced level of lead, providing the products are all certified in accordance with the WaterMark Certification Scheme.
