A landmark regulation is changing how drinking water plumbing works across Western Australia. Here's what every property owner and renter needs to know — and what you can do right now.

Lead-Free Products Mandated
All new water supply plumbing work in contact with drinking water must use Watermark Certified Lead-Free Products. This is now law in Western Australia.
Strict Lead Content Limits
Products containing copper alloy — such as brass — installed or replaced after this date must meet the "Lead Free" definition: a weighted average lead content of no more than 0.25%.
Three-Year Transition Period
A transition period began on 1 May 2023, during which Lead-Free Products were progressively introduced to the market to allow industry and homeowners to adapt.
Legal & Financial Consequences for Non-Compliance
If a landlord fails to comply with the new Western Australia plumbing law, they face serious legal and financial repercussions. Ignorance of the law is not a defence — the consequences are binding and enforceable.
Mandatory Rectification Costs
Landlords will be required to pay for the removal and full replacement of any non-compliant plumbing products at their own expense — with no ability to recover costs from tenants.
Fines & Penalties
Failure to adhere to mandated plumbing standards can result in significant financial penalties. In Western Australia, breaches of plumbing regulations can lead to fines of up to $5,000.
Rectification Notices
A plumbing inspector has the authority to issue a formal rectification notice requiring non-compliant work to be fixed by a specified date. Compliance with this notice is legally binding.
Voided Insurance
Insurance claims relating to water damage or plumbing failure may be voided if investigators determine that non-compliant or illegal materials were knowingly used in the property.
Disciplinary Action
Landlords who attempt to circumvent compliance by using unlicensed tradespeople for plumbing repairs can be prosecuted for permitting unlicensed plumbing work — a serious offence under WA law.
How Lead Gets Into Your Body Through Tap Water
Lead contamination from household plumbing is invisible, tasteless, and odourless — which makes it especially dangerous. According to Prof. John , there are two key points in every home where lead routinely enters the body.
Even small, repeated exposures over time can have serious health consequences — particularly for children, pregnant women, and the elderly. The risk is real, and it starts at your tap.
Kitchen Water Tap
Drinking kitchen tap water or cooking food with it creates a direct lead ingestion pathway into your body — one of the most common and frequent routes of exposure.
Bathroom Water Tap
Gargling after brushing teeth, rinsing your toothbrush, or using bathroom tap water in your oral care routine allows lead to enter through incidental ingestion — multiple times a day.
There are two water tap sections in a house where lead usually gets into our body through ingestion — the kitchen tap and the bathroom tap. Both create a direct pathway for lead contamination.
