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.

Need a Plumber You Can Rely On?

We’re available 7 days a week across Sydney, ready to tackle any plumbing job, big or small.
Count on fast response times, licensed professionals, and upfront, honest pricing with no hidden surprises.

We just moved into our new home and walked in to find 2 leaks coming from the downstairs bathroom ceiling. We called The Plumbing Paramedics and they sent Kyle over. He was friendly and a good communicator. He was thorough when seeking to find the leak. He was able to locate the issue in a damaged upstairs toilet by performing a leak detection test. He removed the damaged toilet and installed a new one for us. If you want an efficient plumbing service and clear communication from office staff, call The Plumbing Paramedics.

We recently experienced a plumbing emergency with water leaking from our ceiling and called Plumbing Paramedics for help. Kyle and Josh arrived promptly and quickly identified the source as a burst pipe. They were professional and knowledgeable throughout, taking the time to clearly explain the issue before proceeding, and completed the repair along with installing a new pressure valve in under 90 minutes. As a family with young children, we greatly appreciated their efficiency and the peace of mind their work provided. We highly recommend them and will use them again!

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.

Frequently Asked Backflow Prevention Questions

Backflow testing is a compliance requirement, so it’s normal to have questions. Here are some of the most common queries we get about testing, certification and devices.

Annually, by an accredited tester, with the result reported to your water authority.

Your water authority follows up, and continued non compliance can lead to penalties. The test is far cheaper than the process that follows missing it.

If you have received a testing notice, you have one. Otherwise we can check on site.

We will tell you whether it needs servicing or replacement, carry out the work, and retest.

We handle the lodgement.

Yes. Multi site and strata portfolios are normal work for us.
