Why not use PEX instead of PVC for a sprinkler system, as well as for 
all house plumbing needs?  With all the publicity and discussion 
around the negative aspects of PVC I never see PEX offered as a 
reasonable alternative.  Does it have carcinogenic qualities?  What 
is the downside to using PEX ?  Certainly reasonably handy homeowners 
can build a system themselves with this product.

I learned to my distress PEX can not be used in solar water systems 
because it can't take the heat, distressed because I embedded it in 
my walls and to the roof in preparation for just this.  But 
otherwise, what is bad about it?   Sacie
