a continuing problem. There's a difference in the basic hydrant
construction, too (I say for the sake of Californians):
In the colder climates, the hydrants are dry-barrel; the actual valve is at
least four feet below grade to prevent freezing. (When the hydrant is shut
down, the remaining water drains into a gravel bed below the frost line, so
the hydrant remains functional.)
A New York State Fire Instructor told me once that the movie scenes where a
car hits a hydrant and there's a column of water are bogus. Wrong. Bogus in
the Rust Belt, but not in the sunnier climates, where the hydrant valves are
in the hydrant top.
Jones snap apparently was scarcely ever used outside the Philadelphia area,
still used some places there. Not a bad connector, in terms of easy and
positive connection, but you need a tool to get it apart (true, sometimes
you need a tool for threaded couplers, too), and I think firefighters just
need to twist something (although the Storz [which I spelled wrong earlier]
and Barcelona have advantage in that they have no moving parts, springs,
etc.).

* The fire service is rife with "traditional" terms; here's another one. The
"steamer" connection on the hydrant--the big one--is where the steam-powered
fire engine would connect a suction hose in order to get enough water
supply. (The prior hand-powered pumpers needed only a 2.5-inch connection,
because that's all the crew could pump, supplying one 2.5 line with a
straight-bore nozzle. The steamer was a hugely powerful engine/pumper in
comparison--but was completely eclipsed by the gasoline-driven pumper, and
today's engines!--Wow!)

"second alarm"
Actually I know of one very small town in NJ that has Jones Snap on their
hydrants. 2 2 1/2" outlets with a threaded Steamer connection. Every one
around them has Snap thread adapters.
The Steamers are the real issue since everyone seems to have thief own
thread cuts and no standards.
