Fixing Burst Pipes
If there is a water leak because of a burst pipe, you should turn off the water at the street meter ASAP. It’s usually under a circular metal cover about 12 to 18 inches in diameter out near the sidewalk. If you can do this before we arrive, this will help reduce the damage caused to your home.
Refer to the pictures below for assistance.


To do this, you will need two simple tools that you can pick up at your local hardware store. They are inexpensive and can save you from having extensive water damage.
The first tool, to remove the water meter lid, is a water meter box lid key. Some lids have a simple locking mechanism to prevent accidental or unwanted tampering with the water meter. Other lids may not have any sort of locking mechanism, so you can usually get the lid off with a big flat blade screwdriver. You can buy a box lid key from places like Lowes or Home Depot.
The second tool is what you use to turn off the water supply to the house. It is called a curb key.
You can also buy a combination curb key and meter box key; however, it requires more physical effort to use as it’s harder to get the leverage needed to turn the water meter valve off or on.
