In the event of a plumbing emergency, it’s good to know how to quickly cutoff the water from its source. Take some time to locate the shutoff valves for your sinks, toilets, dishwasher, washing machine and water heater. Your best bet is locating the main water shut-off valve in your home. This turns all the water off in the house. Put a tag on the valve, so you and other people in your home can easily find it.
