What Is Backflow Prevention And Why It's A Legal Requirement
Backflow prevention protects the public drinking water supply from contamination when pressure changes pull water backwards through the network.
Under AS 2845 and NSW water authority requirements, most commercial, industrial, multi-residential and irrigated properties must have a testable backflow prevention device installed, and must have it tested and certified every 12 months by an accredited tester.
We handle the whole cycle: assessing the hazard rating, installing or upgrading the correct device, testing it annually, repairing it when it fails, and lodging the paperwork with the authority so nothing lands back on you.

Backflow Frequently Asked Questions
Backflow is the unwanted reverse flow of water from a property back into the drinking water main. A backflow prevention device is a one-way barrier that stops contaminated water — from irrigation, fire services, cooling towers, chemicals or wash bays — entering the public supply.
