Arctic air has been plunging into Minneapolis causing the temps to plummet. The extreme cold is tough on your home and your house's plumbing. Once a pipe freezes, it creates an increase in pressure which can lead to a pipe bursting. That can cause significant damage to your home.
Typically your homeowners insurance covers damage caused by a burst pipe, but you need to verify coverage with your agent. There are limitations to coverage as well. If your plumbing is not well maintained and failed due to wear and tear, or if the temperature in the home isn't adequate to prevent freezing.
