Coldest Weather This Winter This Weekend

It is forecast to be 15 degrees tonight and 17 degrees tomorrow night. I’m not positive, but I believe that it hasn’t been below 22 this winter. If you have a vanity on an outside wall, especially if it is upstairs, it would be a good idea to open up the doors so the air can circulate. My toilet supply line is on an outside wall, but the vanity isn’t, so I don’t worry much until it gets down to about 5. But I’ll still be sure the vanity doors are open and that the bathroom door itself remains open during the night.
