A Backflow Preventer Device is an approved assembly, which uses check valves within the device to prevent cross-contamination of the water system occurring. Backflow devices also prevent water from reversing the direction of its flow keeping contaminants from backing up into your water system, thus keeping your water safe with a backflow device.

The Indiana Department of Environmental Management and local ordinances require that each backflow have a mandatory test and certifications completed annually by a licensed cross-connection controI device inspector*. Backflow prevention devices can be found connected to your fire sprinkler systems, domestic water supplies, irrigation systems, dental equipment, boiler systems, and more.

*Some cities require Bi-Annual testing, please check with your local water authority for their requirements or inquire with an NIB associate
