I was just asked a question by a local AHJ....there is a light
hazard bldg
with cpvc pipe hung using ATR 15-17' long. When the pressure was
relieved
the system moved so much they are afraid it is not stable enough to
operate
properly if a head activated.
I know the requirement for vertical restraint near the sprinkler
heads, but
what if the pipe system is so flexible that there is enough lateral
movement
to allow the heads to pop up above the ceiling?
Thanks,
Greg
