Backflow occurs when water flows in the opposite direction to which it is originally intended to flow.

If backflow occurs, it causes pollutants and chemicals to enter the supply of drinking water.

It is the property owner’s responsibility to ensure that the correct backflow device is installed on your property.

The purpose of a backflow prevention device is to ensure that water from the property cannot draw back into the drinking water supply.

The type of backflow prevention device that is required for a property depends upon the risk rating of the property with the potential hazard.

The device should be tested annually for routine maintenance and to check it is operating correctly.
