An inspector finds that a backflow assembly was installed but never tested by a certified tester. What documentation closes this item?
a.A passing test report from a certified backflow tester filed with the jurisdiction
b.The installer's invoice
c.A photo of the device
d.The permit card alone
解析
A newly installed backflow assembly must be tested by a certified backflow tester and the passing test report filed with the water purveyor or jurisdiction to prove it functions. The device's presence alone is not sufficient; performance must be verified and recorded. Annual re-testing is typically required thereafter.
