Backflow valve testing water supply contamination

It's important that we keep our water supply free from contaminants. That's why we have backflow valves present on high-risk properties, like commercial buildings. We are licensed to carry out the mandatory annual testing of backflow valves and replacement if required.


If you need a reliable plumber in Joondalup who is licensed in testing and replacing backflow valves, call Calvin’s Plumbing and Gas on 0411 358 890.
