Yep, I think they froze under the ground, as the pump and accompanying pipes are in the cellar, carefully wrapped and with a heater on it. The next place the pipes appear are about 6 ft. away in my laundry room/bathroom~where we have no water, even though the pipes have a heater on them and the room is toasty warm. So..somewhere in that 6 ft. of space is a problem, I would guess.
We have not been successful in getting a thaw going. This is why I am taking my income tax money and finding myself a good hand pump for this extra well next to the house. No freezing of those pipes!! That way, I can flush commodes, cook, drink, water animals, water my garden from this well if the other is frozen or low. :/
