How do I know if I Have a Leak on my Property?

Watch the video to learn the easy how-to steps involved using your water meter to check for a leak from San Juan Water District water efficiency staff member Ken Kirkland.


To check for a leak, turn off all water-using devices inside and outside your home. Lift the small metal lid on top of your meter box. There is a leak-detecting dial on the face of your meter with a pointer inside it. If the pointer is moving, even slightly, and you do not have any water running, you could have a leak.

For help locating a water leak, call us at (916) 791-2663 for a landscape irrigation review. We’ll check your indoor and outdoor plumbing for leaks and provide suggestions for fixing them. Plus, we’ll tell you about other water-saving techniques. We even offer a one-time credit for leaks within a single billing period.
