Hi, I'm leasing a farm in northern ont. The water going into the barn is frozen. the pipe comes out of the ground outside the barn then goes through the wall into the barn. I have replaced the pipe heater wires that were not working except for the one on the pipe outside.Before it got cold I put a wood box around the outside pipe and insulated with pink fiberglass and then shavings and blown insulation (removed from a friends house) I am assuming that the wire on the pipe outside is not working. Other than taking everything off the pipe outside and putting on a new wire/heating the pipe, is there anything I can do to unthaw this pipe??? I'm wondering if I paint the box black if it would absorb heat from the sun to get the water moving again???? the box is on the east side of the barn so gets sun till around 10:30 or so. it is really cold out (-20 C/-4F today)and I don't want to waste time doing something that won't work/help? As it looks now i have to haul buckets until spring. Suggestions please......
