How It Works

Certified testers visit properties on annual cycles, perform pressure tests on backflow assemblies, submit results to the local water utility, tag devices, and quote repairs when valves fail. Revenue comes from recurring tests, repair labor, parts markup, reminder programs, and property-manager portfolios with dozens or hundreds of devices.
