What is backflow?

Backflow is the unintended flow of water from a potentially polluted source into a potable water supply, backflow is caused when the water pressure from the main drinking water supply is lower than the water pressure in the internal plumbing system. This may be caused by back-pressure or back-siphonage, which may occur when there is a burst or ruptured water main.

Furthermore backflow prevention devices must be tested after installation, maintenance or repair and at intervals not exceeding 12 months, by a licenced plumber certified to work on backflow prevention devices. Installations must be compliant with Australian Standard 2845.3.

Why install a Backflow Prevention device?

The community has a right to protection from contaminated water caused from a backflow incident. History shows that, when a community’s water supply is contaminated, catastrophic health effects can occur and many fatalities may result.

The Water Corporation’s policy requires the installation of an approved backflow prevention containment device at the boundary of every water service connection to a property.

Non-compliance notice?

Due to the potentially hazardous nature of a backflow incident, the Water Corporation may serve you with a non-compliance notice to install backflow prevention devices at your property, this can result in penalties of up to $5,000 and $500 per day that you are not compliant.
