What is backflow and backflow prevention?

The term backflow refers to the reverse flow of unwanted contaminated water that makes its way into the main water supply from either a residential or commercial system. This contaminated water will contaminate the main supply if contact between the two is made.

Backflow prevention is the device that is installed to stop the cross-contamination from occurring by not allowing the contaminated water to head back into the main supply.

Adequate backflow prevention is not only a compliance issue, it can help protect employees, families, and neighbouring properties from contaminated fresh water and the risk of life-threatening disease.  That’s why it can be so important to choose a professional plumbing company with more than 30 years experience of servicing the backflow prevention needs in Sydney.  Our plumbers are fully trained, licensed and insured.  Not only that, but you can be sure of professional, on-time service at a time of your choosing.

Potential sources of water contamination include:

Air-conditioning units

Chemical injection areas

Fire hose reels (FHR)


Painting booths


Swimming pools

Vehicle/bin-washing bays

And more
