Me thinks he is referring to the drain portion of the sprinkler system and not to a draining system.

CPVC is also not explicitly addressed so some think it does not require seismic protection and WONG

Ruling by whom?

Every pping system has a particular classification or Importance Factor. If the drain system, depending on what it's conveying, has the higher factor then maybe but for normal drains, I can't see it.

More info needed.

Just read an interesting "ruling"

Seismic is to be provided for drain piping as if it were system piping.
Guess cause it is? Or because it is not excepted?
Maybe a proposal should be written, or was this really the committee's
intent?
