it seems every year pipes freeze in a different place. Water coming into the barn, not a pump problem. We installed a heating coil along the pipe through the barn and wherever exposed, because of extensive problems. It's plugged in!!!. We have a rather unique water flow thanks to previous owners. The house because it is on the same well as the barn, has no water coming into it. The water source comes in a north basement wall and by deduction this might be where the problem starts. We have had severe winters before, here in Canada and never had this problem. It's Saturday night. Husband is not home for another week. By the way, no other pipes seem to be frozen in the house. What do I do???? Hope to hear from you.
