Backflow testing Brisbane for homes and businesses
Annual testing of testable backflow prevention devices, with the results lodged for you. Plus repairs, replacements and TMV servicing on the same visit.

Backflow testing in Brisbane
A backflow prevention device stops water that may be contaminated from flowing back into the drinking water supply. They’re fitted where there’s a risk of that happening, such as commercial kitchens, childcare centres, medical and dental clinics, irrigation systems, fire services and many industrial and commercial sites.
Testable backflow devices have to be registered with the local council and tested at least once a year. If you own or manage a property with one, that annual test is your responsibility. PlumbCore tests, maintains, repairs and replaces backflow devices across Brisbane and South East Queensland.

Live childcare, clinical and retail sites
A lot of our backflow and TMV work happens on sites that are open. Our team is Blue Card and police checked, and we plan the short water shut-off around your operation so it doesn’t disrupt children, patients or customers.
Property managers and body corporates
If you manage several sites, we can keep track of when each device is due and test them on schedule, so nothing slips past its due date. You get a report for every device, ready for the owner or the committee.
Price
Backflow testing is quoted per site, based on the number and type of devices. Call 1300 165 358 or send us your last test report and we’ll come back with a price.
