Re: Copper vs Pex vs Cpvc
There are three topics to avoid in mixed company: politics, religion, and types of pipe.
That said, my first preference is PEX, followed by copper, followed by CPVC. I don't like CPVC because it does get brittle (crumble in your hand is an exaggeration). Copper may have issues with certain types of water. PEX will last forever as long as its not exposed to sunlight (UV), and the pipe is freeze resistant.
Note that each manufacturer of PEX has their own fittings, and will only warranty the installation when the fittings and pipe are their own brand, and installed according to their instructions. At least one brand provides different lengths of warranty depending on whether or not the installer has received manufacturer certification. In all cases it requires special tools or "shark bite" type fittings, and for a large job buying the special tools will be cheaper than using shark-bites.
They are called "shark bite" fittings 'cause that's what they do to your wallet.
