How to Find and Shut Off Main Water Shut-off Valve
In case of a plumbing emergency, it is always a good idea to educate yourself on how (and where) to turn off your main water supply. A ruptured line or burst pipe through your house is hazardous, unsafe, and potentially cost you thousands in water damage.
In severe cold weather, the water in your pipes can freeze. When water freezes, it expands and can burst the pipe, not matter how thick or strong it may be. Learn how to prevent frozen pipes here; but, if it’s too late and the pipe has already burst, turn off your main water valve as fast as you can to prevent further damages.
Being able to contain the situation as soon as possible will greatly help with damage control and allow a wider window of time for help to arrive (if the situation calls for it). Everyone in your home should know exactly where the water shutoff valve is located and how to turn it off.
Additionally, if you are going to be away from your home for an extended period of time, it is highly recommended that you turn off the main water valve.
Where is the main water shutoff valve located?
This is the million-dollar question. Your main water shutoff valve could be located in several different areas. If you have a home with a basement and crawlspace, it is probably located on an interior wall near the front of the house, where the water comes in from the water meter. In this case, it is most likely hiding in plain sight. If your home was built on a slab, the valve might be located near the hot water heater or inside your garage.
If the valve can’t be found inside the home, the next thing to do is contact your city emergency line and as ask them immediately come to your home to close the water. This will be the first step needed to be taken before contacting any plumber.
Turning Off The Main Water Shut-Off Valve
Stopping the flow of water is easy. If you have a round “wheel” valve, twist it clockwise until it stops. If you have a handle-type valve, turn it one-quarter turn until the handle is perpendicular to the pipe.
WARNING: old water valves can be damaged and corroded. Only use your hand to turn your water valves on or off. If you cannot do it by hand, call a professional plumber.
