In certain situations we have shown water hammer can blow anything apart. Cut groove is better but really that has more to do with schedule 40 vs. light wall. By the way normal burst pressure for CPVC is around 1400 PSI in 2" size.

Top Myers had some interesting claims on standpipes where that happened. You out there Top? Seem to remember something about cut groove being less susceptible than roll grooves.
