Nik,
We cover our insulated copper pipes with the 4" plastic corrugated
drain pipe available at Low's or Home Depot. After the pipe's are insulated we
run this drain pipe from one end to the other. It takes two people, we try to
avoid using 90 degree fittings instead two 45's or use flex copper. Its hard to
get the drain pipe around a 90 degree elbow.

Esteemed Wrenches,
What is your preferred method for running thermal lines underground? We are
about to start a sizable ground-mount system and want to make sure we do this
right. (I've already seen it done the wrong way, the dirty way, and the hard
way.)
Thanks in advance for any feedback.
Best,
Nik
