Today, I found out my walls are literally 2mm thick with no insulation behind them. Explains the 46 degree warmth in my home. Also, the pipes froze solid..even the large 10 inch toilet one. Basement's flooded with nice, cold water.Add the bathroom, too as well as the joining closets and out into the living room... Thank God I have no rugs here.. Toilet lines froze so badly, that the water didn't stop running, BUT the bowl wasn't draining due to freezing.... It's -7 degrees down in the basement right at this time.. Apparently the heat lamps I set up, to keep the pipes from freezing, were turned off.. I think one kid is to blame, but who knows, damages are done.... Tomorrow, I'm skating in my own basement on a slick, new sheet of ice...
