I remember some years ago, when Horizontal sidewalls QR were first used here
in NZ, in a new five star hotel they had a similar incident where a guest
hooked a suit on a hanger over the bulb. It went off and flooded down two or
three storeys. ( Which proves that fire rated floors sometimes leak)
Most THINK that the AWWA recommends BFP's on ALL firelines, especially deadened
lines over 100 feet, but the AWWA does NOT recommend backflow protection on
hydrant only lines.
For I am not ashamed of the gospel , , because it is God’s power for salvation
to everyone who believes... HCS Romans
The 2006 Uniform Plumbing Code 603.4.16.1requires backflows in lines to FP
systems. RPZ's are required for systems with chemicals like antifreeze or AFFF
and double checks for others. It says they are not required for private hydrant
only lines that comply with city water main and AWWA

If my memory hasn't fully failed me, I think there was some generic wording
in the Uniform Plumbing Code years ago that could be interpreted that way.
Had a battle with a local plumbing inspector at the time and lost.
Otherwise, haven't had anybody get bent over it.
Anybody know if the IPC
