Backflow Device Testing

Backflow devices are also required to be installed on all new or renovated commercial buildings.
Why do I need my backflow device tested?
Contaminants or stagnant water can sometimes infiltrate these systems which can lead to bacteria growth. If a problem arises in your water system that may cause the pressure to drop like a water main break, hydrant flushing, or water leak, the bacteria-laden water can sometimes make its way into your drinking water. The backflow testing device prevents this from happening.
