A backflow prevention device is self explanatory it is a device that prevents contaminants from entering our drinking water supply or backflowing.
It is a requirement to install backflow prevention devices on plumbing services where it is possible to contaminate the water service line.
These are some of the common types:
Each backflow prevention device should registered with your local council
Each testable device should be tested at least once per year by a licensed plumber, who carries a backflow prevention endorsement on their license
After each test a written result of the test outcome is then sent to the local council register.
The level of risk of contamination determines the type of device required
