When water starts leaking or a pipe bursts, every second counts. Knowing where your home’s shut-off valves are located and what each one controls can make the difference between a quick fix and significant water damage.
Main Water Shut-Off Valve
The main shut-off valve controls all the water entering your home. In a major plumbing emergency, this is the valve that stops the flow entirely. It’s your first line of defense.
Where to look:
- Along the front foundation wall, where the main water line enters
- In a basement, crawl space, garage, or utility room
- Near the water heater
- If you still have the inspection report from when you purchased your home, it will be listed there
Fixture Shut-Off Valves
In some cases, you don’t need to turn off the water to your entire home. Fixture shut-off valves control water to individual plumbing fixtures and can be used for routine repairs and maintenance.
Toilets
These valves are located behind or just below the toilet tank, typically close to the wall.
Sinks (kitchen & bathroom)
These valves are found inside the cabinet beneath the sink. Most setups include two valves—one for hot water and one for cold.
Appliance Shut-Off Valves
- Water heater: Valve located on the cold-water line above the unit
- Washing machine: Typically found behind the machine in a recessed box
- Refrigerator (ice maker): Located behind the refrigerator or in a nearby cabinet
- Dishwasher: Often installed under the kitchen sink or behind a lower access panel
The Water Meter Box
We suggest that you purchase a water meter key. This is the tool you’ll need to turn off your water at the water meter box. They are inexpensive and available at any home retail store. Just ask for a water meter key.
Locate the water meter box
Your water meter box is usually around 10 feet from the curb near the edge of your property line. It might be hidden.
Using a water meter key, turn this water valve clockwise a quarter turn so that it points away from the water meter and is perpendicular to the pipe. You can also look for two rings on the water valve. When the water is turned off, the two rings will line up on top of each other.
One commonly overlooked issue is that valves left unused for long periods can become stuck. Periodically turning them on and off helps ensure they function properly when needed.
Final Thoughts
Knowing where your shut-off valves are—and making sure they work—can save time, money and stress during a plumbing emergency.
