Calgary homeowners are often surprised to learn that backflow preventers on residential irrigation systems require annual testing by a certified tester — and that failing to test can result in the City of Calgary disconnecting your water service. This guide explains the requirement, the cost, and how J.G. Irrigation handles backflow testing for Calgary clients.
