Who regulates backflow tester certification in Florida

There is no single statewide credential in Florida: requirements are set locally by cities, counties, or water purveyors. Contact your local water purveyor for the rules that apply to you.

The authority for backflow tester credentials in Florida is Florida Department of Environmental Protection (FDEP). Florida Administrative Code Rule 62-555.360 requires each Community Water System's written cross-connection control plan to specify tester qualifications; FDEP itself does not certify testers or set a statewide cycle/CE/fee. The commonly cited "2 years + 1 year grace period" traces only to a university-training-program page, not any official source, so it is excluded. Installers/repairers must be state-licensed plumbing contractors (Ch. 489, F.S.); fire-line testing additionally requires State Fire Marshal certification. Confirm terms with the local utility (e.g. Hillsborough County, Manatee County each run their own tester registration).

How often you need to renew

Florida Department of Environmental Protection (FDEP) does not publish a fixed statewide renewal cycle online. Renewal timing is set by your local jurisdiction.

Continuing education and retesting requirements

Continuing education requirements vary by local jurisdiction in Florida.

Renewal deadline and grace period

The agency does not publish a formal grace period online. Treat your expiration date as hard: Water purveyors generally stop accepting test reports from testers whose certification has lapsed, and many jurisdictions require retaking the full certification course instead of a simple renewal once the credential expires. Confirm the exact grace period, if any, with Florida Department of Environmental Protection (FDEP) well before your expiration date.

How to renew, step by step

Confirm your exact expiration date on your certification card or with Florida Department of Environmental Protection (FDEP).
Complete any required refresher course or continuing education for your jurisdiction.
Submit the renewal application to the local authority or water purveyor that issued your credential before the deadline.
Keep your test kit calibration certificate current: most jurisdictions require annual gauge calibration alongside a valid tester credential.
