What is a Backflow Prevention Device

A backflow prevention device allows water to enter residential or commercial property through the water meter, and prevents potentially harmful polluted water from entering a city’s water supply.

Potable water is the water that flows out of your taps, including your kitchen and bathroom sinks, showers and bathtubs.

When do you need a backflow prevention device?

Your property may have a backflow prevention valve if you have any of the following:

An irrigation system
Fire hose reels or hydrants
Vehicle wash down bays
A commercial or industrial activity or machinery connected to the mains
Water outlets in proximity to pollutants, grease traps or chemicals

3 Levels of Backflow Prevention

Selecting the correct device is determined by the level of hazard as specified in the AS/NZS 3500.1

Individual Protection

The installation of a backflow prevention containment device at the point where a water service connects to a single fixture or appliance.

Zone Protection

For zone protection a containment device is installed at the point where a water service is connected to multiple fixtures or appliances, with no backflow prevention device installed as individual protection downstream of this point.

Containment Protection

A device is installed at the point of connection of a Network Utility Operator’s water supply to a site. Water downstream of a containment device is considered drinking water unless there are unprotected hazards within the premises. The use of individual protection and/or zone protection against these hazards is necessary to prevent contamination of the drinking water supply within the property.

Choosing the right Backflow Prevention Containment Device

Results from testing your device must clearly show

A wide choice of devices can be used to prevent backsiphonage and backpressure from adding contaminants into a water supply. In the DTS (Deemed-to-Satisfy) Provisions, the selection of the correct device is based on the degree of hazard (Hazard Rating) posed by the cross-connection or potential cross-connection. Additional considerations are based upon pipework size, location and the potential need to periodically test the device to ensure correct on-going operation.

Example

Industrial chemical mixing systems would be classified as high hazard, therefore the cold water service would need to be individually protected with a suitable High Hazard backflow prevention valve.
