Backflow Testing & Compliance in Hoppers Crossing

The highest risk sites in Hoppers Crossing are the ones handling water alongside chemicals, food or people in numbers. That means the aquatic and leisure centre, with its pool dosing plant, backwash lines and warm water systems, along with medical and dental centres, commercial kitchens and fresh food tenancies in the shopping centres, car and truck wash bays, service stations, and garden and trade suppliers running irrigation displays. Schools, childcare centres and sporting reserves with in ground irrigation are also commonly fitted with a device. Greater Western Water assesses the hazard rating and notifies the property owner, and once a testable device is installed it must be tested at intervals of no more than 12 months by a plumber holding VBA backflow accreditation.

Age alone does not make a device non compliant, but it does make failure more likely, and much of Hoppers Crossing was plumbed decades ago. Worn check valve seals, corroded relief valves, seized isolating valves and debris from mains work are the usual causes of a failed test on an older assembly, and most can be repaired rather than replaced. Two things do need checking on older installations: that the device still matches the property’s current hazard rating, because a change of use such as a shop becoming a food premises can lift it, and that the device is still accessible, since landscaping, fencing and storage built up around it over the years often has to be cleared before it can be tested at all.

All properties in Hoppers Crossing 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.
