Emergency water shutoffs are located under all of your sinks, at the water heater and at the main water line going into your home. It is important to check these shutoffs to make sure they work properly. Every six months the emergency shutoffs in your home should be turned off and checked for complete shutoff. Hard water deposits and lack of use can cause these valves to freeze up or not turn off all the way. The worst time to find out an emergency shutoff is not working is when you have a leak and need to turn the water off. So taking 15 minutes every six months and checking the emergency shutoffs in your home can save you a big headache in the future.
