It's good for sprinklers, bad for water damage. I was talking to a
fitter (he didn't do the job, but claimed to be familiar with it)
who told me that the building has a fire pump for the standpipe and
the sprinkler piping is CPVC. His thought was that if air is
trapped in the CPVC pipe and there is a water hammer from the pump
starting, that could cause a CPVC pipe to burst. I would think if
the jockey pump is set properly, water hammer would not be an
issue. Any thoughts? Any experience with CPVC bursting due to water
hammer? I know the Fire Marshal fairly well and I'll see what I can
glean from him next time we speak.
