I don't know Todd, this could be plausible. MythBusters anyone? I saw what this piping looked like after a fire many years ago, it was pretty incredible. The building was not completed and the sprinkler system wasn't on, so no water in the pipes, but... The CPVC expanded about 1 1/2 to 2 times its normal diameter, charred black as coal, mangled and twisted, but still intact. Fittings and all. That incident sold me on CPVC.
