Backflow testing

All backflow prevention devices are required to be tested and certified annually.

We can also lodge documentation with the relevant local authority. We also perform any maintenance or repair work as needed.

What are backflow testing and backflow prevention?

The term backflow refers to the reverse flow of unwanted contaminated water that can sometimes make its way from the main water supply in either a commercial or residential system. This is seriously bad if the two water systems meet as it can contaminate the main water system.

Backflow prevention is the device that the team at Hills Irrigation will install to stop the cross-contamination from occurring by not allowing the contaminated water to head back into the main supply. It is a critical service and one that we specialise in. For more information on our backflow testing call us on 1300 984 536
