I don't see anywhere that it is specifically prohibited. But the pipe schedule tables only address steel pipe and copper pipe. So there is nothing to point to in the code that says how many sprinklers can be fed from a particular size of CPVC pipe.

The intent is to maintain the pipe schedule and not provide calculations. I'm not aware of anything, but I don't want this to bite me later.
