Backflow Testing for Mernda Properties
Mernda sits at the northern end of the Plenty Valley and is one of Melbourne’s newer growth areas, with housing estates, schools, sporting reserves and neighbourhood retail built out over the past two decades around the Mernda rail extension. Almost all of its building stock is recent, which means devices here were generally installed at construction rather than retrofitted, and many owners inherit one without knowing. Yarra Valley Water services the suburb.
If your Mernda property has a testable backflow prevention device, annual testing by a VBA-accredited plumber is a legal requirement under Yarra Valley Water regulations. Non-compliance can result in formal notices, fines, and in serious cases, disconnection of your water supply.

FAQ
Common Questions About Backflow Testing in Mernda
Estate housing is frequently connected with a device at the meter, particularly where the build included an in ground irrigation system or a below ground rainwater tank plumbed to the drinking water supply. It is installed as part of the connection rather than something the owner requested, so the first notice from Yarra Valley Water often comes as a surprise.
The device carries its own due date, not the owner. Testing falls due at intervals of no more than 12 months from the last recorded test, so if the previous owner tested nine months ago you have three months left. We can check the date on the register and put the property on our annual reminder program so it does not lapse during the handover.
All properties in Mernda serviced by Yarra Valley 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 Yarra Valley Water on your behalf, within 30 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.
