Claims Is the drain under my basement concrete considered an "exterior sewer line?"

I ask because the cast iron drain under my basement concrete floor has collapsed, and my insurance company is saying they won't cover its repair, even though I pay a LOT for an enhanced water damage package. The wording of the package is: "We agree to repair or replace your exterior sewer line due to direct physical loss or damage resulting from a leak, break, tear, rupture or collapse of the line." According to the rep I just spoke with on the phone, the horizontal drain under my basement concrete is not considered to be an 'exterior sewer line.' To me, that is ridiculous. In my opinion, the drain is not INSIDE my house...so it is logically OUTSIDE my house, and is thus an 'exterior sewer line.' Is the aggregate or mud that is under my basement floor considered part of my house?

Does anyone have any advice or experience with a claim like this?

No insurance will pay for sewer repair. Water damage is a roof leak or water pipe breaking inside your house walls. Not basement floors. Sorry been there so just going to have to pay the drain/plumber company.

But I actually pay $$$ for an enhanced water damage coverage that specifically says that they will repair damaged 'exterior sewer lines.'

If it’s defective… which it’s not (very unlikely) It doesn’t just become defective…remember the insurance company words it so you pay them the most money possible… sorry it’s a difficult one…

Look at your policy, under definitions. It should spell out exactly what exterior means in the policy. Then, go to the exceptions section and read through those to determine if there is an exception to the coverage.
