Automatic Sprinkler Inspection, Testing & Maintenance

Backflow prevention assemblies



Backflow prevention devices and assemblies must be inspected weekly to assure the isolation valves are fully open. If the valves are electronically supervised, the inspection frequency may be increased to monthly.

There should be no leakage or obvious damage to the unit.
