BTW, thanks again for the advice 3 months ago on draining the pipes, and adding anti-freeze to the traps and toilets. I was up all night and had to leave for the airport at 1, and at about 12, it only took maybe 15 minutes to do 8 traps, one after the other. I must admit I didn't do the clothes or dishwasher. Maybe I should have. It turns out I didn't stay the extra month, and nothing got that cold by new years day anyhow. But I was very glad I had done it and could stay another month or two if I had had to, wihout worrying about this.
