Backflow Testing Melbourne

Backflow testing in Melbourne is a specialist plumbing task that can only be carried out by a licensed plumber holding the specialist class of backflow prevention. At Drain Solutions, that is exactly what we hold. We have completed the specialist accreditation course, it has been added to our plumbing licence, and we are fully registered with the BPC to carry out independent backflow testing on your property. If your building has testable backflow prevention devices, we handle the testing, the compliance reporting, and the communication with your water authority so you don’t have to.

Why Backflow Testing Matters for Melbourne Properties

Backflow is when water reverses direction inside your plumbing system. When it happens, contaminated water from industrial processes, fire services, or irrigation can flow back into the drinking water supply. Backflow prevention devices sit in the line and stop this happening, but only if they are working correctly. That is why testing them every 12 months is not optional it is a legal requirement enforced by the BPC and your local water authority. If a device fails its test or has not been tested on time, the water authority can disconnect your supply.

What Drain Solutions Does

We carry out the full range of backflow prevention services for commercial and institutional properties across Melbourne:

Annual Backflow Device Testing

We test all testable devices on site, working to AS/NZS 2845.3 and AS/NZS 3500.1. If a device passes, you get your compliance report the same day. If it fails, we tell you straight away and work with you on the repair or replacement.

Backflow Device Installation

If your property needs a new device installed or an existing one replaced we size it correctly to your property’s hazard rating and install it to the current Australian Standards.

Repairs and Replacements

A failed test means the device is no longer protecting your water supply. We carry common parts and can usually repair or replace on the same visit so your property stays compliant without delay.

BPC Compliance Reporting

Once testing is complete, we lodge the results directly with your water authority Yarra Valley Water, South East Water, or Greater Western Water on your behalf. You get a copy of the report for your records.

Why the Specialist Licence Matters

Not every plumber can legally test a backflow prevention device. The BPC requires that backflow testing is carried out by a licensed plumber who holds the specialist class of backflow prevention. A general plumber or a registered (not licensed) plumber cannot do this work independently. When you hire Drain Solutions for backflow testing, you are hiring the qualified person not a subcontractor, not someone learning on the job. Our licence is current, our accreditation is on the BPC register, and our work is fully insured.

How often does backflow testing need to happen?

Every 12 months. This is set by the BPC and enforced by your local water authority. Missing a test can result in fines or water disconnection.

Who is responsible for getting the test done?

The property owner or their appointed property manager. If you own or manage a commercial or institutional building in Melbourne, this sits with you.

What happens if the device fails?

A failed test means the device is no longer working as it should. We repair or replace it on the spot where possible, then retest to confirm it passes before we leave the site.

Does my property need a backflow device?

If your property has any connection that could allow contaminated water back into the mains fire services, irrigation, industrial processes, or medical equipment then yes. If you are unsure, we can assess your property and advise you.

Annual Reminder Service

We track your testing schedule and contact you when the next test is due. No paperwork falls through the cracks.
