Route

Backflow Testing Route

Annual water-safety compliance in route form

Bottom line

Strong cash-flow candidate with manageable operations.

Backflow testing routes inspect and certify backflow prevention devices for restaurants, medical offices, schools, apartment buildings, and commercial properties. The surprising angle is that many municipalities require annual tests, turning a simple field-service visit into a recurring compliance route with repair/install upsell.

How It Works

Certified testers visit properties on a recurring schedule, test each backflow assembly, submit compliance reports to the city or water authority, and quote repairs when devices fail. Revenue scales through route density, municipal reminders, multi-location accounts, and add-on plumbing work.
