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.

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.
