Testing • Repair • Installation It wasn’t too long ago that backflow preventer valves were not required on fire sprinkler systems. A regular check valve or alarm check valve would do the trick.
Even though there were never any reported problems with this arrangement, water companies became more concerned with the possibility of the contaminants in the public water supply.
Virtually all sprinkler systems that tie into city water supplies have backflow preventers installed today.
