Main Water Line
In the event of a burst pipe, turn off your main water line immediately. There are two ways to turn this off.
1) Turn the valve on the main water line pipe that exits the ground and enters the home. (Mine was next to the irrigation system/back flow preventer).
2) Turn the valve off at the water meter in the underground green rectangular box next to the road. You may need a wrench. If there is a leak detected in your home, you will see a water droplet symbol on the meter screen.
