Essential knowledge in a deep freeze: How to shut off your water
February 2, 2011

The powerful winter storm that's just made a mess of just about everything in the eastern half of the United States has exposed a lot of places to extraordinarily cold temperatures, and one of the consequences is that places that usually don't have much to fear from frozen pipes suddenly do. That makes it essential that homeowners know how to shut off the main water supply to the house. Frozen pipes can burst (because water has that odd property that it expands when it freezes), and when they do, they can cause entire houses to flood. That's an especially large risk right now in places where insulation is more of an afterthought than the life-and-death matter it is here in the Upper Midwest, since a lot of places are getting exceptional cold and snow.
