I share your concern. I live in the Kansas City area, and the weathermen are predicting -14 degrees for Monday night/Tuesday morning. We have a mini-split in the kitchen and the heat rating is only -5 degrees.
I checked the internet and a plumber said to leave both hot and cold water pipes running, and not just with a drip, but a goodly stream.
We will bring up the small heater from the basement and aim it into the kitchen cabinet with the pipes, just do what we can do, give it your best shot, etc.
Subzero weather freezes streams, insulate, heat tape your pipes, open your cabinet doors so you can heat them. Running water through the pipes might work mid 20s. Teens and subzero won’t do jack. Insulate the stud cavities.
Burr!!! We are also in the area. Used to live in Olathe and miss it very much.
Received a call from the insurance company with tips on avoiding freezing pipes!
It will be cold in KC!
