Plumbing code standards and notes

The Plumbing Code of Australia (PCA) is the technical standard for all plumbing and drainage work in NSW and all plumbing and drainage work must comply with the PCA. The PCA sets out the requirements for the design, construction, installation, replacement, repair, alteration and maintenance of plumbing and drainage installations.

The PCA has two provisions for plumbers and drainers to achieve code compliance. One option is for the work to be done under the ‘Deemed to Satisfy’ provision which means that it has been done in accordance with AS/NZS 3500. The other is the performance based provision where work (usually designed by a hydraulic engineer or consultant) meets or exceeds the requirements of AS/NZS 3500.

Copies of the PCA are available to download from the Australian Building Codes Board or for the requirements of submitting a performance solution, download the Guideline for plumbing and drainage: Installing code compliant work and performance solutions (PDF, 91.44 KB).
