We used the PEX system in a recently built house.  I believe every 
positive thing Lawrence has to say about it is true (chlorinated 
water is not a problem).  But be aware there are several 'systems' 
out there and the tools required to compress the rings (to hold the 
fittings together) are proprietary to the specific system.  PEX 
tubing comes in several sizes btw.  I gather it can not be used for 
solar hot water because it won't expand properly.  Let me know please 
if I'm wrong about this latter point.  Sacie
