our pipes freeze if it gets to 27-28 or so.
Kemma, is your meter and everything outside? I think I heard some places down south have the meters outside and then if there is a cold snap, makes them more susceptible to freezing and bursting.
A lot of our snow birds turn their water off at the meter, empty the pipes, and keep the heat on very low when they are gone for the winter to keep the pipes from freezing.
