How Do I Shut Off the Water to My House?
To shut off the water to your house, you generally need to locate the home’s main water shutoff valve and turn it to the closed position. Knowing where this valve is before a plumbing emergency happens can help you limit water damage from a burst pipe or major leak.
Short Answer
Look for your home’s main water shutoff valve where the main water line enters the property. Depending on the home, it may be located in a basement, crawl space, utility area, garage, or another accessible location.
Turn the valve clockwise to close it if it is a traditional wheel-style valve. A lever-style valve is generally closed when the handle is turned so it is perpendicular to the pipe.
If you cannot locate or safely operate the main shutoff, contact a qualified plumber for assistance.
What This Means for Customers
The main shutoff valve controls the incoming water supply to the house. Turning it off can stop or greatly reduce the flow of water to plumbing fixtures throughout the property.
There may also be individual shutoff valves underneath sinks, behind toilets, near appliances, or around other plumbing fixtures. These smaller valves control water to individual fixtures rather than the entire house.
Knowing the difference can be useful during a plumbing problem.
Where Is the Main Water Shutoff Valve?
The exact location varies from house to house.
Common places to look include:
- Near where the main water pipe enters the house
- Basement utility areas
- Crawl spaces
- Garages
- Mechanical or utility rooms
- Near a water heater or other plumbing equipment
- Other accessible areas close to the property’s incoming water line
In some homes, the main shutoff may be outside the building or near the property’s water service connection.
If you recently moved into a home, locating the main valve and identifying how it operates is a useful precaution.
How to Shut Off the Main Water Supply
Once you have identified the main shutoff valve, determine which type of valve you have.
Wheel-Style Shutoff Valve
A traditional wheel-style valve is generally closed by turning the handle clockwise.
Turn it carefully rather than forcing it. If the valve is stuck, damaged, or difficult to operate, do not apply excessive force.
Lever-Style Shutoff Valve
A lever-style valve is generally closed when the handle is turned so that it sits perpendicular to the pipe.
Again, do not force a valve that appears damaged or stuck.
After closing the main valve, open a faucet briefly to help relieve pressure and confirm that the water flow has stopped or significantly decreased.
How to Shut Off Water to One Fixture
You may not need to shut off the entire house for a small problem involving one fixture.
Individual shutoff valves are commonly located near:
- Toilets
- Bathroom sinks
- Kitchen sinks
- Washing machines
- Some water-using appliances
- Other plumbing fixtures
Closing the appropriate fixture valve can stop water to that fixture while leaving the rest of the home’s water supply available.
If the individual valve does not work or is leaking, the main water shutoff may be necessary.
What Should I Do During a Major Water Leak?
If a pipe bursts or a major plumbing leak occurs, shutting off the main water supply can help limit the amount of water entering the plumbing system.
Move people and belongings away from the affected area when possible.
If water is near electrical outlets, appliances, wiring, or electrical equipment, do not enter standing water or touch electrical components. Contact an appropriately qualified professional if there is an electrical safety concern.
After the water is shut off, contact a qualified plumber to identify and repair the source of the leak.
What If I Cannot Find the Shutoff Valve?
If you cannot locate your home’s main water shutoff, check areas where the main water line may enter the property.
You can also ask a plumber to help identify the valve and explain how it operates.
Do not randomly turn valves if you are unsure what they control. Some valves may serve specific plumbing equipment rather than the entire home.
If you are dealing with an active leak and cannot stop the water safely, seek professional plumbing assistance promptly.
When to Contact a Professional
Contact a plumber if you cannot locate the main shutoff valve, the valve is stuck, or there is a major leak that you cannot control.
Professional assistance is especially appropriate when:
- A pipe has burst
- Water is flooding an area of the home
- The main shutoff valve will not close
- The valve is damaged or leaking
- You cannot identify the source of a major leak
- Water is near electrical equipment
- A plumbing fixture continues leaking after its local shutoff is closed
- You need help identifying your home’s main water shutoff
A plumber can help locate the appropriate valve and address the underlying plumbing problem.

Frequently Asked Questions
Where is the main water shutoff valve in my house?
The main shutoff is often located near where the main water line enters the property. Depending on the home, it may be in a basement, crawl space, garage, utility room, or another accessible area. The exact location varies, so check your home’s plumbing layout if you are unsure.
Which way do I turn the water shutoff valve?
A traditional wheel-style valve is generally closed by turning it clockwise. A lever-style valve is generally closed when the handle is perpendicular to the pipe. Do not force a valve that is stuck or damaged.
Do I need to shut off the whole house for a leaking sink?
Not necessarily. If the sink has a functioning individual shutoff valve, you may be able to turn off the water to that fixture only. If the local valve does not work or the leak is elsewhere in the plumbing, the main water supply may need to be shut off.
What should I do if my main water valve is stuck?
Do not force a stuck or damaged shutoff valve, as this could cause additional plumbing problems. If you cannot close the valve during a leak, contact a qualified plumber for assistance.
Should I turn off the water if a pipe bursts?
If a pipe bursts and you can safely access the main water shutoff, closing it can help limit additional water flow. Stay away from electrical hazards and standing water near electrical equipment. After shutting off the supply, contact a plumber to address the burst pipe.
