A National Plumbing Regulators Forum (NPRF), with representatives from all States and Territories, was established in 2002 to develop a Plumbing Code of Australia (PCA). In 2004, the NPRF’s PCA 2004 was published. It was adopted in the Australian Capital Territory, Queensland, South Australia, Tasmania, and Victoria.
PCA 2004 was designed as a performance-based code and was set out to be compatible in its structure and operation with the Building Code of Australia. PCA 2004 called up, or referenced, the 2003 AS/NZS 3500 – Plumbing and Drainage series of standards, along with other relevant standards, as a means of providing Deemed-to-Satisfy solutions to the Performance Requirements.
Those jurisdictions which did not adopt PCA 2004 continued to directly regulate the use of AS/NZS 3500 or used other independently developed regulation.
