Annual inspections and testing are required including all of the following:
Reduced pressure devices, doublecheck devices, pressure vacuum devices, and air gaps are all tested and certified by licensed personnel. All devices are tested for proper pressure relief of backflow checks, relief valves, correct air gaps, and proper placement for either containment or isolation.
Certification must be reported to the water authorities immediately after the testing is completed. This reporting is done automatically by Complete Fire Protection. We test and certify all types of devices whether it’s on fire sprinkler systems, domestic water supplies, irrigation systems, and any other device used for isolation within a building.
Please confirm with the local authority having jurisdiction to confirm any specific inspection interval. Different jurisdictions may have different requirements.
