Fire Sprinkler and Backflow Devices

fire sprinkler and backflow devices

Gold Standard in Structure Protection

Civilian death rates from fire are 87% lower in properties with sprinklers that operate than in properties with non-working or no sprinklers, per NFPA. And the Safe Drinking Water Act protects our potable water supplies from contaminated fire sprinkler backflow—when installed and maintained properly.

The Two Types of Backflow

  • Caused by an increase in pressure in the downstream piping, reversing the normal flow direction.
  • Reversal of the normal flow in the piping, resulting in negative pressure in the supply piping.

Note: Backflow device(s) are tested on an annual basis, unless the water purveyors require the RP or RPZ to be tested semi-annually. Inspection of backflow devices is not required as part of the sprinkler inspection.
