Backflow Prevention Testing and Certification Sydney
We deliver backflow prevention across Sydney and we’re available 7 days a week for urgent jobs.
We ensure your water quality remains safe and compliant
Annual testing, done and lodged, so the reminder letter stops coming
If your property has a testable backflow prevention device, it has to be tested every twelve months by an accredited tester and the result reported to your water authority. Miss it and the letters start, and eventually so do the penalties.
We test, certify and handle the paperwork across Sydney, the Hills District and the north west.
Who needs annual backflow testing
Testable devices are typically required where there is a hazard rating that calls for one. That commonly includes commercial premises, food businesses, medical and dental suites, properties with fire services, irrigation systems, rainwater tanks plumbed to the house, and residential properties with certain fixtures.
If you have had a letter from your water authority, you have a testable device. If you are not sure, we can tell you on site.

What Sydney Locals Say About Us
What the test involves
The device is tested against the standard. An accredited tester checks the device performs as it must, using calibrated equipment.
A report is produced. The result is documented with the device details, the readings and the outcome.
The report is lodged. The result goes to your water authority within the required timeframe.
If it fails, it gets fixed. Devices wear. Where a device fails we will tell you whether it needs servicing or replacement, repair it, and retest.
What we do
Annual backflow testing and certification
Scheduled testing with the report lodged for you, so the compliance side is handled rather than remembered.
Device servicing and repairs
Where a device fails the test, we service or repair it and retest.
Device replacement
Where a device is beyond repair or the wrong type for the hazard, we replace it.
New backflow device installation
Installation where a device is required and none is fitted, or where a change of use has raised the hazard rating.
Testing reminders
We can hold your test date and contact you when it is due, so it does not become a letter.
Multi site and strata testing
Multiple devices across a site, or across a portfolio, tested and reported together.
Why property managers and business owners use us
The paperwork is handled. The test is only half the job. The report has to reach the water authority, and we do that.
We can fix what fails. Some testers only test. We are licensed plumbers, so a failed device gets repaired rather than turning into a second contractor and a second visit.
Scheduled, not chased. Put the site on a schedule and the annual obligation looks after itself.
Commercial and strata experience. Multiple devices, multiple buildings, one report set.
