Testing Requirements

Regular Backflow Testing Requirements

Why do Backflow Prevention Devices have to be tested after installation, repair, maintenance or on a 12 monthly basis?

Devices need to be tested periodically to ensure that they function properly. This is a requirement of the manufacturer and it takes into account of the fact that the internal seals, springs and moving parts are subject to fouling, wear or fatigue. Testing requirements are identified in the Australian Standards AS 2845.3-2010 and also AS 3500.1-2003.

Annual Testing

Each Backflow Prevention Device must be tested on an annual basis. This is a condition of connection to the water supply. It means that the Backflow Prevention Device is maintained and continues to operate effectively.

The annual test will ensure the drinking water is safe to drink.

If a Backflow Prevention Device is defective or faulty, it may

a) not prevent a contaminated source entering the drinking water supply

b) cause water to be wasted through a leaking device

c) impact on the water pressure supplying the property

d) worst case scenario Backflow can cause death.
