Australian StandardsStandards Australia, formerly the Standards Association of Australia, has for some time published technical standards relating to plumbing and drainage matters. In the late 1980s, several existing plumbing standards were consolidated and a set of updated Australian Standards was published in 1990 with the objective to provide: ‘acceptable technical standards for the design and installation of plumbing systems throughout Australia’. This is the AS 3500 series. Although designed as a national code, its adoption over the years following was disconnected and heavily varied.
The Plumbing Code of Australia 2004A 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 ACT, Qld, SA, Tas and Vic.
The PCA 2004 was designed as a performance-based code, and was set out to be compatible in its structure and operation with the BCA. PCA 2004 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. The jurisdictions that did not adopt PCA 2004 continued to regulate the use of AS/NZS 3500 or used other independently developed regulation.
