Mine is only 3 to 4' down, but I'm in NE Ohio not VT. The transition doesn't have to be in a heated enclosure, but that's by far the best. I took a 3' section of plastic culvert pipe and made an insulated cover for it and put it where the pipe comes out of the ground. It's worked fairly well but I did have some times when the sap lines let loose before the 15' sections above ground were thawed enough to pump much thru. I suspect that is why my pump got weak at the end of the season.
