What Is Backflow?
Contaminated water flowing the wrong way into the public mains
The risks are real: serious illness, injury claims and significant liability exposure for the building owner. A properly tested backflow prevention device is what stands between your building and that risk.
Your Legal Obligation
Annual backflow testing is compulsory — not optional.
- RAS/NZS 3500 + National Plumbing & Drainage compliance
- RAnnual inspection, test and certified report
- RReport lodged with your water authority on your behalf
What We See In Melbourne Buildings
The three compliance gaps that catch owners out
01
No annual test records
