The kitchen is one of the most important rooms in the home. It’s where you prepare meals, clean dishes, and store food. However, if there’s a plumbing emergency or a leak, it can cause serious damage. That’s why it’s important to know how to turn off the water under the kitchen sink. In this article, we’ll explain how to do so step-by-step.
Shutting Off the Main Water Supply
The first step is to locate and shut off the main water supply. This is typically located in the basement or outside the house near the water meter. To turn off the main water supply, you’ll need an adjustable wrench. Once you’ve located the main water supply, use the wrench to turn it clockwise until it’s completely closed.
Turning off the Valve Underneath the Sink
The next step is to locate and turn off the valve underneath the sink. This will be connected to the cold and hot water supply lines. To turn off the valves, simply turn them clockwise until they’re completely closed. You may need to use an adjustable wrench to get enough leverage to turn off the valves.
Removing the Faucet Handle
Once the valves are shut off, it’s time to remove the faucet handle. This will give you access to the nut connecting the supply lines to the faucet. To remove the handle, use a flathead screwdriver to loosen the screw holding the handle in place. Once the screw is removed, the handle should come off easily.
Unscrewing the Nut Connecting the Supply Lines
Now that the handle is removed, you’ll need to unscrew the nut connecting the supply lines to the faucet. To do this, use an adjustable wrench to loosen the nut. Once the nut is loosened, carefully remove it from the supply lines.
Disconnecting the Supply Line from the Shutoff Valve
With the nut removed, you can now disconnect the supply line from the shutoff valve. To do this, hold the supply line with one hand and turn the shutoff valve counterclockwise with the other hand. Once the valve is loose, carefully pull the supply line away from the valve.
Closing the Shutoff Valve
The final step is to close the shutoff valve. To do this, simply turn the valve clockwise until it’s completely closed. Be sure to double-check that the valve is completely closed before proceeding.
Turning off the water under the kitchen sink is an important step to take if you’re dealing with a plumbing emergency or leak. By following the steps outlined above, you can easily shut off the main water supply and the valve underneath the sink. Remember to always double-check that the valves are completely closed before proceeding.
