I think this theory is incorrect. My GF is selling her mother's house
and is
reluctant to shut down the heat and drain the pipes over the winter.
(We live in the Northeast.) She was told by an "expert" that the
plaster will crack. I regularly shut my heat off for the winter at my
summer home, and have never had cracks in my plaster ceilings.
I'd like your comments. Obviously sudden temperature changes
might do it, but not one slow drop.
Thanks in advance for help.
