FAQ

Preventing backflow is crucial for protecting public health. Contaminated water can carry harmful bacteria, viruses, chemicals, and other substances that can cause illness. Backflow prevention devices create a barrier to stop this contamination.

These are mechanical assemblies designed to prevent the reverse flow of water. Common types include Reduced Pressure Zone (RPZ) valves, Double Check Valve Assemblies (DCVA), Pressure Vacuum Breakers (PVB), and Atmospheric Vacuum Breakers (AVB). The type of device needed depends on the level of potential hazard.

Many residential, commercial, and industrial properties require backflow prevention devices, especially those with potential cross-connections like irrigation systems, fire suppression systems, pools, and certain industrial processes. Local regulations often dictate where these devices are needed.

The installation process typically involves site assessment, excavation to accommodate the backflow prevention device, proper connection to the water lines, and backfilling.

Local water authorities often have regulations outlining requirements for backflow prevention. You can also contact us for an assessment of your property’s potential cross-connections and backflow risks.
