Backflow FAQ

---

A Backflow Preventer Assembly is an approved device, which uses check valves within the device to prevent contamination of the water system, and prevents water from reversing the direction it flows in.

The Illinois Department of Public Health and local ordinances require that each backflow prevention assembly be tested and certified upon installation. It is mandatory to be tested and certified annually thereafter, by a licensed cross-connection control device inspector. Backflow prevention devices are commonly found on fire sprinkler systems, domestic water supplies, irrigation systems, dental equipment, boiler systems, and more.
