It really just depends on the type of policy you bought and what is the cause of the damage to the drain pipe. If it broke from freezing or another covered peril it's probably covered.
Most homeowners Insurance Policies will not cover foundation damage nor pipes embedded in in or below a slab foundation unless the damage is the result of a covered peril.
There are endorsements that some companies offer to provide coverage for foundation or ground movement as well.
Insurance will not typically cover a broken furnace due to the wear, tear and deterioration exclusion. Some reasons insurance company will cover a broken furnace if it was vandalized, damaged by fire or water.
That would depend on your policy JUST like what type of car insurance you have.
Most home owners policies will cover it unless the water from the broken pipe did not cause any damage to the property.
Probably not. It should cover any damage done by the break, but not the break itself.
No. Unless the foundation problem happened because of an earthquake or flood (and you have insurance to cover both catastrophic events), then your insurance will not cover something that has degenerated with time.
"Flood Insurance" will cover damage resulting from a Flood. Homeowners Insurance will not.
No. Homeowners Insurance does not cover the owners default on a mortgage note.
I beliieve it does.
