How often does a backflow preventer need to be inspected?

Backflow preventers should be inspected and tested on the schedule required by your local water authority. The exact interval varies by city and device type, so a technician will confirm timing during an on-site visit. We provide backflow testing and same-day service in areas like Glendale Heights, Schaumburg, and Elgin.

Quick checks:

• Look for the last test date on the device tag.
• Watch for notices from your city or water provider.
• After plumbing changes, schedule a test.
