Backflow Prevention devices are installed to ensure that drinking water supplies are not contaminated when there is a cross connection in a water line.
In compliance with Sydney Water a Backflow Prevention Containment Device must be tested annually in order to prevent problems with your water supply such as:
- Changes in water supply pressure
- Contaminated water entering your clean water supply, or
- Wasting water caused by a leaking device
Installation and testing of any type of Backflow device can only be done by a licensed plumber with Backflow Prevention accreditation.
