State rules
New York
New York’s sanitary code, 10 NYCRR section 5-1.31, requires suppliers of water to have cross-connection control programs and to assure protective devices are inspected and tested by a certified backflow prevention device tester at installation, after each repair, and annually. The State Department of Health’s certification instructions say every person who tests backflow prevention assemblies shall be certified under that section. Since 2011, Department-approved training providers issue the certification of course completion. The Department’s FAQ says the Bureau of Water Supply Protection discontinued issuing the certifications. A tester’s certification is valid for three years. Initial certification is an approved initial course. Renewal is an approved renewal course before the expiration date.

The regulation says initial and renewal certifications are issued by a Department-approved entity when the applicant proves satisfactory completion of a Department-approved training course. The Department may require a written, oral, or practical examination if it finds that reasonably necessary, and the result may be the sole basis for approval, disapproval, or suspension. Any installation, service, maintenance, testing, repair, or modification must also follow the relevant county, city, town, or village plumbing code. The state certification does not erase a local plumbing-code limit. Records of tests are reviewed and kept by the supplier of water.
The FAQ says a person whose certificate has been expired for less than one year takes a renewal course. A lapse of more than one year means the person must repeat the initial course. The person cannot test assemblies until recertified. The Department’s course page lists approved providers and says initial and renewal courses are also approved for renewal credits for certified water operators. That operator-credit note does not turn a water-operator certificate into a backflow-tester certificate. The tester still needs the backflow course completion from an approved provider.
A customer should ask for the current certification of course completion, the provider’s name, and the expiration date, and should confirm the supplier of water will accept that provider. The three-year term means an old card may not be enough. No single statewide test fee is stated in the certification instructions used here. Training providers set their own course charges, which are not copied here because they are not a state license fee.
