Sunshine, 3020
Backflow Testing for Sunshine Properties
Sunshine began as an industrial centre and has grown into one of the west's main commercial and transport hubs, with Hampshire Road retail, a busy station precinct and major infrastructure work tied to the airport rail link. Older factories and workshops still sit behind the shopping strip, and new medical, education and residential development continues to fill in around them. Both the older industrial stock and the newer commercial premises commonly hold testable backflow prevention devices under Greater Western Water.
If your Sunshine property has a testable backflow prevention device, annual testing by a VBA-accredited plumber is a legal requirement under Greater Western Water regulations. Non-compliance can result in formal notices, fines, and in serious cases, disconnection of your water supply.

Seven Steps to Stay Compliant in Sunshine
Every Sunshine test follows the same clear process. Our VBA-accredited plumber handles the testing, paperwork, and submission so your property stays compliant.
Preparation
We confirm the device location, access requirements, and previous test details before starting at your Sunshine property.
Shut-off
We isolate the relevant water supply safely so the device can be tested without disrupting more of the property than necessary.
Test setup
Calibrated test gauges are connected to the device test ports and checked before pressure readings are taken.
Performing the test
We test each check valve and the relief valve on RPZ assemblies to confirm the device is operating to specification.
Recording results
All readings, device details, and pass or fail results are recorded for your Greater Western Water compliance report.
Issue certificate
Your compliance certificate is issued on the day of the test, with any repair recommendations explained clearly.

FAQ
Common Questions About Backflow Testing in Sunshine
If a testable device is fitted, yes, regardless of the age of the building. Older workshops around Sunshine often had a device installed years ago at the meter and the paperwork has not followed the property through a change of owner. Greater Western Water still holds the device on its register, and it must be tested at intervals of no more than 12 months. We can locate an unrecorded device and bring it back onto the register during the first visit.
A failure does not automatically mean replacement. Most failures come down to worn seals, debris on a seat or a pressure irregularity, and we carry common parts so minor repairs can often be done on the same visit and the device retested straight away. Where the device cannot be repaired we set out the replacement options before any work goes ahead.
All properties in Sunshine serviced by Greater Western Water are required to have testable backflow prevention devices tested at intervals of no more than 12 months. Missing the annual window can trigger compliance notices and, in serious cases, disconnection of your water supply.
Only a plumber holding VBA accreditation in backflow prevention can legally test a device and issue a compliance certificate. A standard plumbing licence is not sufficient. Aussie Backflow holds VBA Licence No. 28465 with full backflow prevention accreditation.
