Backflow valve testing water supply contamination

July 15, 2019

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.
