Emergency: Your First 10 Minutes
Turn off your main water valve
Turn off the main water valve to stop damage. It’s often near the water meter in the basement or mechanical room. If you cannot find it fast, shut off the nearest fixture valve you can access.
ELECTRICAL SAFETY NEAR WATER
If water is near outlets, appliances, or the electrical panel, avoid standing water. Switch off the breaker for that area only if it’s safe. If you are unsure, wait and call.
DOCUMENT, THEN CONTAIN
Take a few clear photos or a short video for insurance. Use towels and buckets to contain water if possible. If drains are backing up, avoid running more water in the home.
