Must meet both criteria. The 1½" hose station is available for untrained persons thus the pressure limit.

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.
