Independent guide — not a contractor. Planning information only. Confirm licences, waterproofing, and quotes with qualified trades and the relevant state authority.
| Check | Why | Where to read |
|---|---|---|
| WaterMark where it applies | Plumbing products used in AU are expected to be certified | ABCB WaterMark scheme |
| WELS rating | Water use on taps, showers, dishwashers, toilets | waterrating.gov.au |
| Serviceable aerator | Hard water scales a cheap nozzle into a drip | Ask what unscrews for descaling |
| Finish vs service | Chrome you can descale vs a coating you cannot touch | The hard-water post |
WaterMark and WELS are certification schemes, not product endorsements. Hard-water regions need serviceable aerators more than a finish story.
