The Master Plumbers & Gasfitters Association of Western Australia Since 1901

We want to remind our members about Industry Bulletin 173, which Building and Energy issued to inform the industry about changes that came into effect on 1 May 2026

Following a decision by the Australian Building Codes Board (ABCB) to further delay the mandatory installation of lead free plumbing products, Building and Energy has published an update to Industry Bulletin 171 for the WA plumbing industry.

Building and Energy has developed a new fact sheet providing industry guidance on the requirements for installing gas appliances in WA.

Due to an increase in detections of minor gas leaks, Building and Energy have issued new testing guidance for gasfitters.

Plumbers and gasfitters who are asked to connect LP gas cylinders can help keep consumers safe by making them aware of the different valve types and new rules for warning labels.

Building and Energy's Industry Bulletin 171 is the regulator's formal notification that from 1 May 2026, it will be mandatory in WA to use lead free copper alloy products and material in contact with drinking water.

In less than 15 months from now, it will be illegal to install copper alloy plumbing products with a lead content above 0.25 per cent, so you should be running down your inventory of old products.
