Thanks for the info, guys. I'd never heard about CPVC getting brittle. I don't know if I'll be doing this or not but we've been negotiating on a house sale. If we do it, I have some plumbing to replace.
With PEX, is it worth the cost of the clamps to use the clamp rings instead of the expensive Sharkbite fittings? Of course it depends on how many you have to do but I'll be doing a whole house.
