With subzero temperatures on the way this weekend, water departments and companies are reminding people to leave water on somewhere in buildings where pipes are prone to freezing. Karen Cotton with Illinois American Water says it doesn’t take much to prevent frozen pipes.

That also can prevent the service line to your home or business from freezing. Another tip is to open a door to let heat into the space where the pipes are if that's possible. If a water pipe freezes, turn off water to the building and use a safe heat source to patiently thaw it. Don't try to hurry things up with a candle or torch.
