Who regulates backflow tester certification in Connecticut

Certification is regulated at the state level: one credential is valid across Connecticut.

The authority for backflow tester credentials in Connecticut is Connecticut Department of Public Health (DPH), Drinking Water Section. The widely repeated "3 years, proof of 50 tests, 3-hour course, $69" figures appear only on third-party CE-course marketing sites, never on portal.ct.gov, the official DPH application PDF, or the RCSA regulatory text. Officially confirmed: INITIAL certification requires a $154 application fee and a 20-contact-hour (2.0 CEU) DPH-approved NEWWA course. RCSA Sec. 25-32-14 sets a 3-year renewal cycle for water operator classes, but backflow testers are certified under the separate Sec. 25-32-11(e), which is not listed in that renewal table, so the 3-year figure cannot be officially attributed to backflow testers. Confirm renewal cycle/fee directly with CT DPH before publishing.

Renewal deadline and grace period

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 Connecticut Department of Public Health (DPH), Drinking Water Section well before your expiration date.

Complete any required refresher course or continuing education for your jurisdiction.
Submit the renewal application to the agency before the deadline.
