How to find your main water shutoff
The main shutoff controls water entering the home. Locations differ by building, so it is worth finding it before an emergency.
What you can check
- 01
Look near where the water service enters the house, often in a basement, utility area or near the water heater. In apartments, ask the building manager.
- 02
Identify and label the main valve without changing its position. Confirm its purpose with your utility or building manager if you are unsure.
- 03
Keep the path to the valve clear and let household members know where it is.
Safety first
Never force a valve that is seized, damaged or leaking. Do not operate a utility-owned street valve unless your water provider directs you.
When to ask for help
If you cannot identify the valve or it will not operate easily, ask a plumber to inspect it.
