How do I plumb an outside line to a roof deck faucet?
Well... since nobody responded.

I used 2 10' straight pipes as well as a 10' of soft copper tubing, and a bunch of couplers and 45 degree elbows.  I used copper clips and masonry screws to attach the pipe to the wall and to the upper hanger, and used sweated joints througout.  Was much slower than using PEX!
