A failed assembly is repaired and retested until it passes, and a copy of each record goes to the city within seven days of the work.

Under City Code 24-6, the city decides the method from the activities on the premises: an air gap for hazardous activities, a reduced-pressure assembly on every domestic connection near the meter, and double check assemblies on water-only fire sprinkler lines.
