Form 9 Backflow Lodgement QLD — Testing & Compliance
Complete guide to Form 9 backflow prevention device testing and lodgement in Queensland — plus how to lodge digitally with TradeDesk.
What is Form 9?
Form 9 is the testable backflow prevention device testing report required under the Queensland Plumbing and Wastewater Code. Whenever you test a registered backflow prevention device — typically annually — you must complete a Form 9 and submit it to the local council that has jurisdiction over the property.

Frequently Asked Questions
Who can complete a Form 9 in Queensland?
Only a licensed plumber with current backflow prevention testing endorsement (BPI/BST) can test a testable backflow prevention device and complete the Form 9 report.
How often does a backflow device need to be tested?
Testable backflow prevention devices must generally be tested at least once every 12 months. Some devices and risk classifications require more frequent inspection — always check the council's specific requirements for the property.
Which Queensland councils does TradeDesk email Form 9 to?
TradeDesk maintains a directory of Queensland council backflow inboxes including Brisbane City Council, Gold Coast, Sunshine Coast, Logan, Ipswich, Moreton Bay, Redland, Toowoomba and others. If a council isn't yet in the directory you can enter the email address manually and TradeDesk will save it for next time.
Is the digital Form 9 accepted by Queensland councils?
Yes — Queensland councils accept Form 9 lodgements via email as long as the form is fully completed and signed by the licensed tester. TradeDesk produces a Form 9 PDF that mirrors the layout councils expect, with the tester's licence number, signature, and test results.
Do I need to keep my own copy of the Form 9?
Yes. TradeDesk automatically saves a copy of every lodged Form 9 to the device record, along with a record of the email sent and the recipient. You can download the PDF or resend the email from the device page at any time.

TradeDesk's Form 9 lodgement is included in the Pro plan, which starts with a 21-day free trial — no credit card required. After the trial, Pro is $79/month or $790/year (save $158).
