Good try partner. As a Master Plumber licensed in my state and very experienced in all types of plumbing piping I can tell you with authority that copper is much harder to install than CPVC or PVC. Having said that let me also assure you I do not find copper difficult to work with at all. A couple weeks ago I even soldered a 1 1/4" copper line that was FULL of water. Bet you can't do THAT! I can almost solder in my sleep. I can silver solder too. Bet you don't know the difference or that there is a difference.
I don't need no plumber. I also enjoy popping the bubbles of know-it-alls who are spouting off incorrect advice in my field. And anyone who thinks copper is as easy as CPVC is not doing something right or has nver worked with either.
PS. I happen to hate CPVC with a passion.
