What would you like to know -- I can say, I know quite a bit about it now... Wirsbo (Uponor), Rehau, etc... PexA, etc...

If you asking if it is better than PB, Duh. YES! If you're asking if it is better than copper -- well, better -- I can't say since we don't have as much history... I CAN tell you that if you are going to use a crimp and clamp type PEX you're a fool. Stick with either the Expander (ProPex) method or the APR type.

If you want more info -- let me know.
