More adventures in landlording; we were in bed at a bed and breakfast when we got a call that one of our furnaces was out. Thank goodness for Home Service Plus; they came out and fixed it. Twice, because the first fix wasn't quite right.
And then we got a text that the water had stopped flowing in a half bath. Fortunately, they have more than one bathroom in that house, so it wasn't a total emergency. Turns out that half bath is over a crawl space, and one that was well insulated to keep heat from leaking into it from the basement. Seriously people; don't put plumbing on uninsulated exterior walls, especially when it passes through an uninsulated crawl space first.
P got to thaw out the pipes, since I had places to be. But I got there just in time to help out with the heat tape.
