If you ever have to turn off water FAST, you will need to know where your master valve (also called main water cut-off valve) is located.

Your master valve is usually found where the water supply enters your home; perhaps in the basement, the crawl space or near the water heater. Once you find the master valve, test it to see that it is the right one and that it works properly. If you close it, the water supply coming into your house should stop. Label the valve with bright colored tape or a sign. Make sure everyone in the home knows where the master valve is located.

When an emergency such as a major leak or broken water pipe occurs, the first thing you will need to do is shut the water off. If you act quickly, you may prevent costly water damage to your home and valuables.
