Backflow Testing
Backflow prevention testing and certification for commercial and industrial properties across Melbourne.

Annual backflow testing for commercial properties, done on schedule with council-compliant reports.
If your property has a backflow prevention device, it legally needs testing every year by an accredited plumber. We test all common devices, lodge the paperwork, and put you on a reminder cycle so you never miss a compliance date.
We run annual programmes for facility managers and commercial property owners across Melbourne - one less compliance job to think about.
Where a device fails, we carry common parts and in most cases repair and retest on the same visit, so your property never sits out of compliance waiting on a second appointment.

Common questions.
How often does backflow testing need to happen?+
Annually, by law, for testable devices. We track your due dates and book you in automatically so compliance never lapses.
What happens if my backflow device fails the test?+
We quote the repair on the spot and in most cases fix it the same visit, then retest, so your property is never left sitting out of compliance.
Do you lodge the paperwork with the water authority?+
Yes. We complete the test, lodge the report with your water authority on your behalf, and send you a copy for your records. One less compliance job to think about.
“Finally I found a reliable, on-time, gets-the-job done plumber! All I want is a tradie to give me a reasonable quote, to turn up, to communicate with me, to do the job efficiently and to not charge like a bull - and Joolz does all of the above! Very happy to recommend him.”
