Backflow Testing for Williamstown Properties
Williamstown sits on the bay about 11 kilometres south west of the CBD and combines a heritage streetscape with a working maritime economy. The commercial centre runs through Nelson Place and Ferguson Street, where cafes, restaurants, boutique retail and professional services trade alongside marine businesses, boatyards and dockyard operations on the foreshore. Hospitality and marine servicing are the two property types in Williamstown most likely to hold a testable backflow prevention device under Greater Western Water.
If your Williamstown 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.

months max between tests, as required by Greater Western Water

FAQ
Common Questions About Backflow Testing in Williamstown
Usually yes. Hull washing, fuel handling, chemical storage and non potable water used around slipways all create connections that Greater Western 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 rather than a simpler double check valve.
Testing requires the supply to the device to be isolated briefly, which is disruptive for a cafe or restaurant mid service. We work around trading hours where the shutdown would interrupt a venue, and confirm an appointment window when you book so the site can plan around it.
All properties in Williamstown 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.
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 Greater Western Water on your behalf, within 14 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.
