<DIV><FONT face=Arial size=2> 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.</FONT></DIV>

Wrenches,<BR><BR>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.)<BR><BR>Thanks in advance for any
feedback.<BR><BR>Best,<BR>Nik<BR><BR><BR></SPAN>
