Well I still prefer my sweated copper, as a serious weekend warrior thats done LOTS with only one problem child. AND IT WAS A PROBLEM.
Even my garage Air system is plumbed in copper.

BUT, I have wanted to put one of those hot water recylers to the wife's sink. It take for ever to get hot water there, and the shower. Copper would be a bite, real bite, to run the return. PEX looks like a solution, and these things give an easy transition.

Note, I have looked at the recylers that use the existing cold for a return, but the wife isn't happy about loosing the cold water. Women !!!!

But thanks for the info !!!
