Backflow is the unintended reversal of water flow from a non-potable source into the potable water system. It can introduce contaminants such as chemicals, fertilizers, or bacteria into drinking water, posing serious health risks.

Common devices include Reduced Pressure Zone assemblies (RPZ), Double Check Valve Assemblies (DCVA), Pressure Vacuum Breakers (PVB), and Atmospheric Vacuum Breakers (AVB). Each serves different risk levels and installation conditions.

Property owners are typically responsible for maintaining and ensuring their backflow assemblies are tested and functioning. Municipalities often enforce testing and require submission of test reports.

Most jurisdictions require annual testing. Some sites with increased risk may need more frequent testing. Check local regulations or consult our team for guidance.
