How do I turn off the water in my home if I have a major leak?

The main water shutoff valve controls the flow of water into your home.

Find It.  Locate the water meter lid in your yard, then follow a straight line to your home.  That’s typically where the water line enters the home and where you’ll find the main shutoff valve.

• In most homes, the water shut-off valve is in the basement, a crawl space, utility closet, or in the garage, under a concrete slab.

• Can’t find the main valve? Consider calling a licensed plumber to locate or install one.

Test It.  Once you locate the main valve, test it. Turn off the valve and check all the faucets in your home.

• If no water comes out, you found it! If water is still flowing, try again.
• Most appliances have separate shutoffs but only the main shutoff valve will turn off all the water in your home.
• If the valve doesn’t work, you may need to contact a plumber.

Tag It.  Once you find the main water shutoff valve, tag it and make sure other family members know where it is.

• Use a brightly colored, waterproof ribbon You can also call 502.583.6610 to request a Louisville Water shutoff tag. 
• Turn the valve a couple of times each year to ensure it operates smoothly when needed.
