Carl and I live in the same state. My three 250' runs (4", 2.5" and 1") are
made of the gray PVC used for buried electrical service and were installed
by a professional crew. The trench is over 4 feet deep, so it's below the NH
frost line (don't ask me about the three seams of ledge we had to punch
through.) The pipes angle down a hill that drops 35 feet over the course of
the run. They're terminated at both ends with Greybar weather-sealed utility
boxes. No splices in the cables, either. Two years and no water problems --
so far.

73, Dick, WC1M
