While it isn’t something that happens too often, there is a possibility of a pipe springing leak in your home. It could be from some amateur home improvement where you drill or saw into a pipe and all of a sudden water starts gushing out. If you do end up in such a situation, you will quickly have a disaster on your hands. A pressurized pipe can discharge about 14 gallons of water each minute, which will flood your home pretty quickly.
To prevent this from happening, you should first make sure that you are aware of what is behind the wall where you are making a cut. You should also be familiar with the locations in your home where you can turn off the water when this happens. Sometimes the only place where you can go to turn it off is at the main shutoff valve, and while you run to that location, quite a bit of water will have time to leak out.
