Annual Backflow Retest Reminders & 335-Day Advance Recall

Every state and municipal water purveyor enforces annual retesting for cross-connection control devices. From apartment complexes and medical facilities to restaurants and shopping plazas, building owners receive formal notices mandating certification within 365 days of their last test.

If a property manager misses that deadline, the water purveyor issues violation fines and eventually shuts off municipal water service.

Most backflow contractors track annual renewal dates in Excel spreadsheets, paper desk calendars, or whiteboards. This manual approach leaks revenue every season:

• Slipped Deadlines: When testing season gets busy in spring, 11-month follow-up emails get delayed or forgotten.
• Competitor Poaching: Competing testing services reach out to property owners when water purveyor warning letters arrive, stealing established clients.
• Zero Route Conflicts: Automated 335-day advance scheduling prevents route conflicts and overlapping test sessions for the same certified tester on peak route days.

BackflowProof replaces spreadsheets with a mathematically sound recall workflow:

When you close out a certified test in the vault, BackflowProof automatically calculates the 335-day date, walks the route schedule to prevent tester overlap, and lets you confirm next year's annual retest with a single tap.

In addition to annual retest scheduling, BackflowProof generates 24-hour advance reminder notices for property managers and facility directors.

Audit logs in the Reminder Outbox verify that notice emails and SMS messages were generated and delivered, ensuring facility maintenance staff have vault keys and gates unlocked when your tester arrives.
