Who is responsible for the testing and maintenance of the backflow assembly?
It is the sole responsibility of the customer to ensure that the assembly is in satisfactory operating condition at all times. Flagstaff Industrial Waste Monitoring Division will send notices to the customer advising them when an annual test is required on their backflow assembly. The customer must contact a recognized Backflow Assembly Tester to perform the test. If any repair work or maintenance is performed on the assembly, a recognized Tester must retest the assembly immediately and submit the test results to the Backflow Prevention Section.
