You are mis-informed.  The problem is not with the pipe.  It's with one 
manufacturer's plastic fittings.  They have failed and caused catastrophic 
damage.  I know of no problems using PB pipe and copper fittings with crimp 
rings.

I used PB pipe with copper fittings in my house.  It's 5 years old and I've not 
experienced any problems whatsoever.  Unles some new problem is discovered, I'll 
use PB again.
