Stop The Flow!
Put a stop to the flow of water at the source.
Unless the flooding is the result of a natural calamity, identify the source of the water and shut it down or lock it up. The simplest way to stop water flow is to turn off the main water valve to the house. Locate the valve before it floods if feasible so that you can find it quickly in the case of a water emergency.
Turn off the power.
After the source of the water has been turned off, switch off any electrical systems in your home—but don't walk through water to get to the fuse box. If you can't reach the fuse box without stepping in water, call an electrician.
Evacuate the structure.
If a pipe has broken or a sewage leak has occurred, evacuate the premises and seek a dry, safe spot outside your home. It could be in your own backyard or as far away as a neighbor's or friend's house. Check to check that everyone is safe and undamaged, including children, dogs, and anyone else who may have been at the house.
In the event of a natural disaster, consult authorities or listen to local news to find a temporary shelter. Evacuate everyone to the shelter as soon as possible.
