Annual Backflow Testing & Certification — Total Plumbing & Gas
If your building has a backflow prevention device, you are legally required to have it tested and certified every year by a registered Independent Qualified Person (IQP).
Without a current Form 12A certificate from a registered IQP, you cannot issue your annual Building Warrant of Fitness (BWoF) — and without a BWoF, you are in breach of the Building Act 2004. Fines apply.
Most property owners know they need to do this. Few have a reliable system to make sure it actually happens every year.
That’s where we come in.
What’s Included
Annual Backflow Compliance Programme — $300 + GST per device
Full inspection and testing of your backflow prevention device(s) by a registered IQP
Compliance certificate (Form 12A) issued and filed — ready for your BWoF submission
Tamper-proof compliance tag fitted to each device showing test date and next due date
Annual reminder sent before your next test is due — we track it so you don’t have to
If a device fails: repairs carried out by our certified plumbers at standard charge-up rates (labour, materials, and travel), followed by a re-test at $150 + GST
You stay compliant. We handle the paperwork. No surprises.
