NFPA #14 states that when the static pressure at a hose connection exceeds 175 psi, a pressure regulating device shall be provided to limit the pressure to 100 psi for 1 ½" hose connections and to 175 psi for all other hose connections.
What if the standpipe is a Class III utilizing the fully sprinklered building exception allowing 2 ½" hose valves with 1 ½" reducers, caps and chains? Does the pressure need to be limited to 100 psi or 175 psi? Dave David K. Thompson Vice President Allstate Fire Sprinkler, Inc. P.O.
