Ed, et. al.,
PEX stands for PolyEthylene, X(cross)linked. Great stuff if you don't
mind the price of the fittings, which are really expensive compared to
PVC and Cu. Check out the color coded tubing and the manabloc
distribution setup at:

Once I start on the rescue projects in NM I plan to use that system for
all my trailers. Also the studio/darkroom/summer kitchen/workshops in
what now is the stock shed. (Maybe even the house; can you say,
"Believer"?)
