Description

MBIE is amending Acceptable Solution G12/AS1 to limit the maximum allowable content of lead permitted in plumbing products. The amended document will limit the maximum lead content of any product that contains copper alloys, intended for use in contact with potable water for human consumption. This includes products such as pipe fittings, valves, taps, mixers, water heaters, and water meters. The transition period for this change will end on 1 September 2025.

As the transition period extends to 2025, the revised acceptable solution will be published in alignment with the rest of the plumbing and drainage updates in November 2023. 

By announcing this decision prior to the publication of the revised acceptable solution, our aim is to provide certainty and direction to the sector and give manufacturers and suppliers additional time to implement the required change to the effected plumbing products.
