Find Your Main Water Shut-Off
Every home has a single valve that shuts off all its water. Knowing where it is — and being able to close it in the dark, half-asleep — is the most valuable home skill there is.
A burst pipe or a failed appliance hose can pour water into your home faster than you can bail it. The damage is measured in minutes, and the difference between a mop-up and a ruined floor is one valve. That valve is your main water shut-off, and it controls every drop that enters the house.
In a house it's usually where the water line comes in — near the water meter, in a basement or crawl space, in a utility closet, or on an outside wall. In an apartment it may be under a sink or in a hallway closet. There may also be a separate curb shut-off out by the street that the utility controls.
The tragedy is finding it for the first time while water sprays across the ceiling. Locate it today, on a calm afternoon, so that when it matters you are turning a valve you already know instead of hunting for one you don't.

Locate the valve today
Trace where the water line enters your home and find the main shut-off nearby. If you rent, ask your landlord or building manager to show you. Then make sure everyone in the household knows where it is too.
- By the meter, basement, crawl space, or utility closet
- Under a sink or in a closet in many apartments
Learn which way it closes
A round wheel-style valve closes by turning it clockwise, all the way, until it stops. A lever-style valve closes when the handle sits crosswise to the pipe. Try it once so your hands remember the motion under stress.
Keep it working and reachable
Clear anything stacked in front of it, and if the valve is stiff, corroded, or won't budge, have a licensed plumber service or replace it. A shut-off you can't turn is no shut-off at all.
You will never regret knowing where your water shuts off. You may deeply regret learning it too late.
