Known clean-water sources
Examples can include a recently failed potable-water supply line or certain appliance supply connections, depending on actual conditions.
Unknown or contaminated water
Outdoor runoff, long-standing water and unknown sources may present additional hazards. Avoid contact and describe the situation accurately when seeking help.
Conditions can change
The age of the loss, materials contacted and site conditions can affect how a professional evaluates the water and required precautions.
