2. Defects in any tested assembly shall be repaired/replaced within thirty (30) days by same size, type configuration, installation orientation, make and model # (equivalent/substitute) of Lead-Free type from currently USC approved/listed assemblies, and repair/replacement shall be followed by a retest. Retest results shall be submitted to the NYC DEP office with description of repairs, parts and materials used.

3. Failure to submit an annual test report for each approved BFPA is a violation of §20-04(e) and will result in the issuance of a Notice of Violation returnable to the Environmental Control Board (ECB). This may result in the imposition of a civil penalty of up to $1,000.

4. The building-owner or property manager will not receive future reminders of the required BFPA Annual Test Report. The DEP is offering a free service where you can sign up to get email reminders about the testing requirements and required dates for your Backflow device(s). To sign up go to
