Wrap exposed pipes with insulating material. Pipes under kitchen sinks, in crawl spaces, near windows or in unheated basements are areas susceptible to freezing.
Locate your inside water shut-off valve now! The shut-off valve controls all of the water into your home. If a pipe bursts, knowing the location of your shut-off valve and how to turn it off, can save valuable time and prevent water damage.
The shut-off valve may be located in the basement, under the kitchen sink, in a utility closet, near the hot water heater, or even under the house in a crawl space. If you cannot locate or do not have a shut-off valve, call your plumber.
Try turning off your shut-off valve. Then turn on each of the faucets in your house, if no water comes out you found the main shut-off valve. Once you locate the main shut-off valve mark it so everyone in your family can find it should an emergency occur.
If your house has a crawl space, cover the outside vents to prevent winter winds from entering and freezing pipes. Keep the garage door closed if you have a slab foundation. Some water pipes are located under concrete floors in the garage.
