Backflow Prevention

What Is Backflow Prevention?

Backflow prevention protects potable drinking water supplies from contamination caused by the reverse flow of water. Backflow can occur when sudden changes in pressure draw pollutants or non-potable substances back into the clean water network, creating serious health, legal and operational risks.

We specialise in the installation, testing and maintenance of certified backflow prevention devices in accordance with Australian Standards and local authority regulations.

Annual backflow testing is a legal requirement for most commercial and multi-unit properties in NSW. We handle the paperwork end-to-end.
