Mordialloc, 3195
Backflow Testing for Mordialloc Properties
Mordialloc sits on the bay where Mordialloc Creek meets Port Phillip, with a retail and hospitality strip along Main Street, a working boat harbour and marina on the creek, and the foreshore reserves either side. Established housing and local schools fill in behind. Hospitality and marine servicing are the two property types in Mordialloc most likely to hold a testable backflow prevention device under South East Water.
If your Mordialloc property has a testable backflow prevention device, annual testing by a VBA-accredited plumber is a legal requirement under South East Water regulations. Non-compliance can result in formal notices, fines, and in serious cases, disconnection of your water supply.

Preparation
We confirm the device location, access requirements, and previous test details before starting at your Mordialloc 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.

All readings, device details, and pass or fail results are recorded for your South East Water compliance report.

FAQ
Common Questions About Backflow Testing in Mordialloc
Marine servicing usually does. Hull washing, fuel handling, chemical storage and non potable water drawn around slipways all create connections South East Water treats as a medium or high hazard, and a testable device is required to protect the street main. High hazard connections need a Reduced Pressure Zone assembly.
Testing requires the supply to the device to be isolated briefly, which is disruptive mid service. We work around trading hours where a shutdown would interrupt a venue, and confirm an appointment window when you book so the site can plan around it.
All properties in Mordialloc serviced by South East 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.
A failed test does not necessarily mean replacement. Most failures involve worn seals, debris, or pressure irregularities that can be repaired on the same visit. We carry common parts and will retest after any repair. If replacement is required, we will advise on options.
Yes, report submission is included in every test. After testing we submit your compliance certificate directly to South East Water on your behalf, within 20 business days of testing.
Most single-device tests take 20 to 45 minutes. Multi-device properties take longer depending on the number and types of devices. We confirm an estimated duration when you book.
