Well, insurers will often cover you for water damage from burst pipes, but not from flooding. That's because the damage from burst pipes happens at a predictable trickle of people over the course of a year, but damage from flooding happens to tens of thousands of people on the same day. So the amount of money you have to set aside for the two cases is wildly different. Side note: This is also why your life insurance policy is useless in the case of nuclear war :)
