How to submit backflow test reports in Colorado

STATE FORM REQUIREMENTCO-CDPHE

Colorado publishes the CDPHE Regulation 11 sample test report, which BackflowGo fills — individual purveyors may substitute their own form.

Colorado mandates no form — this is CDPHE's Reg 11.39 sample report. Since 2025-07-01 (HB25-1077) the serviced assembly must also carry a physical TAG with the business name/contact, service date & description, and certification number.
