The emergency master shut-off valve is what you will use to shut off the water supply to your home in the event of an emergency. Typically, it is located in the basement, crawl space under your home, or in your garage. It may also be located outside your home by the foundation. Some homes do not have shut-off valves. If you cannot locate your water shut-off valve, or if it appears to be stuck, check with a plumber.

This is particularly important when the weather is cold and there is a risk of frozen or burst pipes.
