Does my homeowners or renters insurance cover water damage from a burst pipe versus a flood?

The source of the water determines coverage. Sudden, accidental internal water damage, like a burst pipe or an overflowing washing machine, is typically covered by standard homeowners and renters policies. Gradual leaks and lack-of-maintenance damage usually are not. Sewer or drain backup is often excluded unless you add a specific backup endorsement, which is inexpensive and worth it.

Flooding from outside, meaning rising surface water, storm surge, or overflowing rivers, is never covered by a standard policy. You need separate flood insurance, usually through the FEMA-run National Flood Program or a private flood insurer, and there's typically a 30-day waiting period. FEMA notes that most flood claims come from outside high-risk zones, so many homeowners should consider it.
