I did a remodel of my own home with CPVC. Great stuff - easy to work with, forgiving if things don't exactly align, and difficult to get a bad joint. Most of my runs were in an attic with cellulose insulation and I didn't want to risk a fire sweating copper up there, so plastic became the material of choice. Didn't require any expensive tool like PEX does. At the time I was living in earthquake country and the added bonus was that CPVC was pretty resistant to movement.
