And again Ed's 80+ year old active brain may be the solution to your problem. What is the soil temperature at 3 feet? At 4 feet? At 5 feet? Up in northern climes we bury deeper and deeper to get below the frost line to where the temperature stays around 50 degrees all year. That 's pretty shallow in the Puget Sound Area but what depth does UG go to in Montana or Manitoba. You may be able to go down, both in depth and degrees, to a stable temperature where your pipe is in a cooler soil temperature.
