How often does a backflow preventer need to be inspected?

Inspection schedules for backflow preventers are set by your local water authority or municipality. Requirements can vary across Chicago and nearby suburbs, so timing depends on local code and your property’s risk category. Green Air Care can inspect, test, and document your device during service and let you know the next due date.

Quick steps:

• Check the last test date on your device tag.
• Ask your water provider for current rules.
• Schedule a professional test and keep the report.
