Changes have been made to the National Construction Code (NCC) 2019 that includes an amendment to the Plumbing Code of Australia (PCA) Volume Three and adoption of AS/NZS 3500.2:2018.

Among the changes to AS/NZS 3500.2 is a restriction on the use of 88° sweep junctions.

This resource should be used to understand the changes made to AS/NZS 3500.2 in detail. Specifically, building practitioners are no longer permitted to use an 88° sweep junction along a graded drain as a Deemed-to-Satisfy Solution under the latest edition of the Australian Standard. The resource outlines what is now an acceptable method of construction according to AS/NZS 3500.2. 

The resource details what should be done in the event that a branch, discharge or fixture pipe connects to a stack. And it outlines situations in which an 88° sweep junction may still be used. 

Lastly, it provides links to extra information on the topic, including a useful technical note produced by the WA Department of Mines, Industry, Regulation and Safety, plus information on changes made to the PCA 2019, which is available at the ABCB website.
