Do These Things While Help Is Coming
Close the main shut-off first. If you cannot find it or it will not turn, the curb stop near the street can shut the supply, though it may need a special key. Next head to the panel, but only if you can get there on dry footing.
Standing water and live outlets are the biggest danger on these calls. If water is touching outlets, cords or a power strip, stay out of that room and tell the dispatcher. Move valuables, documents and medications upstairs or onto high shelves.
Dispatcher tip: Renting and cannot reach your landlord? Shut off the water, take photos, and text and email the landlord with the time, so there is a record that you acted quickly.
