What is Backflow & Why Prevention Matters?
Backflow occurs when the normal direction of water flow is reversed, allowing contaminated water to enter the drinking water supply. This can happen due to sudden changes in pressure within the system.
Backflow prevention devices stop this contamination and protect public health. Because of the risks involved, certain properties and industries are legally required to have backflow devices installed and tested annually.

Backflow devices are commonly required for properties that:
- Have high-risk water connections
- Use chemicals or specialised equipment
- Supply water to commercial facilities
- Connect irrigation, fire services or industrial machinery.
Typical sites include:
- Cafes & restaurants
- Dental & medical clinics
- Hospitals

- Sporting facilities
