Adelaide Backflow Prevention & Testing Specialists
Backflow prevention is a critical part of protecting the safety and quality of your property’s drinking water supply.
When backflow occurs, contaminated water can flow backwards into the clean water system, creating serious health and safety risks for building occupants and the wider community.
At Hall and Baum, we provide professional backflow prevention services throughout Adelaide, including backflow device installation, testing, maintenance, repairs and compliance reporting for commercial, industrial and institutional properties.

What is backflow?
Backflow occurs when water flows in the opposite direction to normal, potentially allowing contaminated water, chemicals or other substances to enter the clean drinking water supply.
What is a backflow prevention device?
A backflow prevention device is a specialised valve installed within a plumbing system that prevents contaminated water from flowing back into the potable water supply.
Why is backflow prevention important?
Backflow prevention helps protect public health by preventing contaminants from entering drinking water systems and reducing the risk of waterborne hazards.

Many commercial, industrial and institutional properties are required to have backflow prevention devices installed depending on the level of risk associated with the property’s water usage.
