Chances are you'll never have a plumbing catastrophe, like a burst pipe. If you do, you can't afford to waste precious minutes searching for the main water shutoff valve. That's why it's crucial for every homeowner to know where this valve is and how to shut it off. The first thing you need to do is find your water meter. The main water shutoff valve is usually close to it. Now, where the meter is located can vary. In colder regions, where pipes could freeze in the winter, the water line usually enters through the floor of the foundation. locate the line entering your home, follow that line and you'll find your water meter. Keep following it and you'll see the shutoff valve. To stop the flow of water turn the valve handle clockwise, so the handle is perpendicular to the pipe. In older homes the shutoff valve is closed using a circular handle. Turn the valve clockwise to shut of the flow of water. In warmer climate like Arizona, the shutoff valve will be outside of the house often near an outside faucet. If it's more convenient, you can have an inside shutoff valve installed.
