Where to find the main water shutoff valve
What tools you need to shut off the water valve
Turning the Water Off
Once you’ve located the shutoff valve and gotten into the box, turning the water off is generally easy. Most shutoff valves require a small turn. You may find you need a good amount of muscle, but because you’re not managing water pressure from this valve, you shouldn’t need to turn it far at all- the settings are on and off and that’s it!
