Do you know the location of your water shut-off valve?
If a pipe breaks, you won't want to waste time finding it then, or, worse, wait for someone to find it for you. In most single-family homes, the shut-off valve is in the basement or in the crawl space, on a wall facing the street.
Make sure everyone in your household knows how to shut off water to your home. Doing so may prevent expensive water damage if a pipe breaks.
