How to turn off the water supply in your home

Imagine a pipe has burst in your home, and while you’re waiting for the plumber to come, water keeps running. With water flowing, every second could mean more repairs and higher water bills. Do you know where the main water shut off valve is and how to turn it off?

Whether it’s for an emergency, just to be prepared, or a remodeling project involving your home’s plumbing, everyone should know where the water shut off valve is and how to turn it off.

Where is the main shut off valve located?

Most plumbing accessories like faucets, toilets, and bathtubs have their own water shut off valves close to them. When minor plumbing problems arise, you can turn the valve behind the fixture to turn the water off.

However, there is a way to ensure the home’s plumbing is turned off all at once in an emergency.

There are several locations the main water shut-off valve can be depending on your home’s age and the climate of your location. Usually, for warmer climates like Sonoma County, the water valve can be found near the home’s perimeter on an exterior wall.

It is not always easy to locate the valve if you’re a DIY plumber, as some houses have the valve inside, outside, underground, or near the property line. Some apartments have water shut-off valves under the kitchen sink, in the bathroom, or near the washer and dryer.


If you cannot locate your water shut-off valve, reference the property inspection report or call your local plumbing company. Your plumber can help find the water shut-off valve and relocate it to make it easier to access if it is difficult to access.

How to turn off the valve

Once you find the valve, turn the wheel handle to the right or clockwise until you can’t turn it anymore to shut off the water. For knife style valves, turn the handle clockwise 90 degrees until it is perpendicular to the pipe.

Knowing how and where to shut off your home’s main water supply is necessary in the event of a burst pipe, water leak, or serious plumbing repair. For plumbing service, repairs, and emergencies, contact our Super Service Plumbing team at (707) 544-6444 today.
