Backflow Prevention Adelaide, done right.
Backflow prevention is critical to protecting your property's drinking water. When backflow occurs, contaminated water can flow backwards into the clean water supply — creating serious health risks for occupants and the wider community.
Hall & Baum provides backflow prevention and testing in Adelaide, covering device installation, testing, maintenance, repairs and compliance reporting for commercial, industrial and institutional properties throughout Adelaide.
Many commercial properties are legally required to have backflow prevention devices installed and tested regularly to comply with SA Water requirements. Our accredited plumbers inspect your system, carry out the required testing and make sure your devices are working correctly — for businesses, schools, healthcare facilities, councils, shopping centres and industrial sites across Adelaide.
We also handle thermostatic mixing valves in Adelaide, commercial hot water in Adelaide and trade waste in Adelaide, so one call covers the whole job. Browse our full range of commercial plumbing services in Adelaide, or book a plumber online in under a minute.

Backflow Prevention questions
Backflow Prevention for Adelaide businesses: what you need to know
These are the questions Adelaide business owners ask us most about backflow prevention, answered by plumbers with 70+ years of local experience.
How often must backflow devices be tested in SA?
SA Water requires testable backflow devices to be inspected at least every 12 months by a licensed tester, with results lodged.
Does my business need a backflow prevention device?
Most commercial, industrial and medical sites do, especially those using chemicals, irrigation, fire services or process water.
What happens if my backflow test is overdue?
SA Water can issue compliance notices. We track your due dates and remind you before each test is needed.
Can you repair a failed backflow device?
Yes. We carry common parts, repair or replace failed valves on site, and re-test and certify the device the same day.
