Armor Fire Protection Inc provides professional inspection, repair, and installation of Backflow Prevention Devices. We are certified to complete Backflow Testing Services in the state of Arizona. If you have domestic water service, an irrigation system, or a fire protection system, you most likely already have backflow devices installed on your property. Your local water agency requires that these devices be inspected on a regular basis. Failure to comply with inspection requirements may result in fines and your water service being discontinued.
