Option 1: Shutting Off the Main Water Supply
If your sink doesn’t have an individual shut-off valve, you can shut off the main water supply to your entire house. This is the most effective way to ensure that no water flows to the under-sink area. Here’s how you can do it:
- Locate the main water shut-off valve. This valve is typically found near the water meter, which is usually located outside your home or in the basement.
- Turn the valve clockwise (to the right) to shut off the water supply. In some cases, the valve may require the use of a wrench or pliers to turn, so be prepared with the necessary tools.
- To confirm that the water supply has been successfully shut off, turn on a faucet in your home. If no water comes out, then you have successfully turned off the main water supply.
While shutting off the main water supply may seem like a more extensive solution, it ensures that no water will flow to any area of your home, including under the sink. It is ideal when you need to work on plumbing repairs or if you suspect a leak in the pipes.
Remember to turn the main water supply back on when you have completed your work. Turn the valve counterclockwise (to the left) until it is fully open. Check all the faucets in your home to ensure that water flows freely again.
Option 2: Using the Shut-off Valve at the Water Meter
If your sink doesn’t have an individual shut-off valve, but you have access to the water meter, you can use the shut-off valve located there to turn off the water supply.
- Locate the water meter. It is usually installed outside your home, typically near a sidewalk or in your yard. If you’re unsure of its exact location, contact your local water authority for assistance.
- Remove the meter box cover, if applicable, to access the shut-off valve.
- Locate the shut-off valve handle or a round valve wheel. It may have a “Water Shut-Off” label or a similar indication.
- Turn the valve clockwise (to the right) to shut off the water supply. You may need to use a wrench or pliers to provide enough leverage, especially if the valve is stiff or hasn’t been used in a while.
- To ensure that the water supply is fully shut off, turn on a faucet inside your home to drain any remaining water in the pipes.
Using the shut-off valve at the water meter allows you to specifically shut off the water supply to your home without affecting the water flow in neighboring properties. This method is useful if you want to work on the under-sink area or address any leaks without impacting the rest of your plumbing system.
Once you have completed your repairs or maintenance, remember to turn the shut-off valve counterclockwise (to the left) to turn the water supply back on. Test the faucets in your home to ensure that water flows properly.
If there is no valve under the sink, you can turn off the water supply to the entire house at the main shut-off valve. This is usually located near the water meter or where the main water line enters the house.
Option 3: Shutting Off the Water Supply to the Whole House
If you can’t access the shut-off valve under the sink or at the water meter, another option is to shut off the water supply to the entire house. While this method is more drastic, it effectively stops water flow to all areas, including the sink. Here’s how you can shut off the water supply to the whole house:
- Locate the main water shut-off valve. This valve is typically found near the water meter or where the main water line enters your home.
- Depending on your home’s plumbing setup, turn the shut-off valve clockwise (to the right) to shut off the water supply.
- Check all the faucets in your home to ensure that no water flows. If there is still water coming out, you may need to turn off additional shut-off valves located throughout your plumbing system, such as near the hot water heater.
Shutting off the water supply to the whole house is a more severe measure, as it affects all water usage in your home. Only resort to this option if you are unable to access individual shut-off valves or if there is an emergency that requires immediate water flow cessation.
Once you have completed your work or resolved the plumbing issue, turn the main water shut-off valve counterclockwise (to the left) to restore water flow to your home. Double-check all faucets to ensure that the water flows properly.
Option 4: Turning Off the Water Supply to the Kitchen
If you want to shut off the water supply under the sink specifically, you can try turning off the water supply to the kitchen. This option allows you to stop water flow to the sink area without impacting the water supply to other parts of your home. Here’s how you can do it:
- Check under your kitchen sink for a shut-off valve. It is typically located on the water line connecting the sink to the main water supply.
- If you find a shut-off valve, turn it clockwise (to the right) to shut off the water supply. It may be a lever-style valve that you can simply flip, or a wheel-style valve that requires a clockwise turn with a wrench or pliers.
- Once the valve is closed, turn on the kitchen faucet to ensure that no water flows. This confirms that you have successfully shut off the water supply to the kitchen.
If you cannot locate a shut-off valve specifically for the kitchen, you might have an older plumbing system that lacks individual valves. In such cases, consider using one of the previous options to shut off the water flow to the sink area.
When you have completed your repairs or maintenance, turn the shut-off valve counterclockwise (to the left) to restore water flow to the kitchen. Ensure that the faucet is closed and check for any leaks or irregular water flow.

By being able to shut off the water flow, you can prevent potential water damage and tackle plumbing issues effectively. The methods discussed in this article provide different options based on your specific situation.
If you have access to the main water shut-off valve, you can shut off the water supply to the entire house, ensuring that no water flows to the under-sink area.

These options are ideal for situations where you need to perform repairs or maintenance without affecting the rest of your plumbing system.
If you don’t have individual shut-off valves, you can still shut off the water supply by turning off the main water shut-off valve or by shutting off the water supply to the kitchen. These methods may be more drastic, as they affect the entire house or kitchen water supply, but they can still effectively stop water flow to the under-sink area.
Remember, once you have completed your work, always turn the shut-off valves back on to restore water flow and check for any leaks or irregularities in the plumbing system. Regular maintenance of your plumbing system, including checking shut-off valves and fixing any leaks, is crucial to ensure its proper functioning and to prevent any potential issues.
By familiarizing yourself with these methods to turn off the water supply under the sink, you can confidently handle plumbing emergencies and tackle repairs without the risk of water damage.
