The BPC Plumbing Technical Bulletin is a quarterly newsletter that provides Victorian plumbing practitioners with up-to-date information about legislative and regulatory changes, education opportunities and industry trends, with a focus on the technical aspects of their trades.
Each newsletter is sent to plumbing practitioners, industry bodies, engineers and subscribers.
A new regulator with new powers
On Tuesday 1 July, the Building and Plumbing Commission (BPC) launched, heralding a new era of stronger building regulation.
The BPC brings key functions related to building and plumbing regulation together under one roof, including registration, inspection and compliance, practitioner discipline, dispute resolution and domestic building insurance.
The BPC will soon be given new powers to address gaps in the regulatory system – these new powers will significantly improve consumer protection. I look forward to working with industry and sharing more details with you as we get closer to their introduction, which is expected to be later this year.
Updated plumbing and drainage standards (AS/NZS 3500 series)
All plumbing practitioners are reminded that from 20 October 2025 you must ensure your plumbing work undertaken is in accordance with the updated standards for plumbing and drainage, parts 1-4 of AS/NZS 3500.1: 2025.
These standards are referenced in the Plumbing Regulations 2018 and Plumbing Code of Australia (PCA).
I urge plumbing practitioners to familiarise themselves with the updated standards and apply it in their work ahead of the 20 October deadline. Learn more about these changes by visiting the BPC's dedicated AS/NZS 3500 series web page .

ESM compliance management and the importance of data and good documentation

As facility managers change over time, crucial information can be lost, leading to potential risks and inefficiencies in the building's operations. This underscores the need for proactive measures to retain and protect vital data.
