I assume that was a result of the Meridian One fire. To this day, the
PRV's are listed as the prime culprit (ie in Wikipedia) instead of
saying the city changed their equipment without addressing the older
installed systems. I first heard that when I talked with one of the
chiefs that investigated the fire but that conclusion was excluded
from the reports. Obviously there were multiple problems but it's
never a good idea to bring only a knife to a gun fight.

As an example of how at least one FD has grown to address this wide
range of standpipe performance (sometimes in the same building),
City of San Franciso trucks and engines carry three different types
of tips. If the ones fitting to the hose packs aren't right for a
particular fire, they can go all the way down to low pressure smooth
bore or straight stream. But it starts with knowing what's gonna
come out and the signage is now a prescriptive requirement of both
13 and 14, and which can be easily retrofitted.
