Why is my basement floor drain backing up?

Should you get a sewer scope before buying a home?
For homes built before about 1980, or with large trees in the front yard, a sewer scope is worth it. A standard home inspection doesn't look inside the sewer line, and in most U.S. cities the buyer will own that line, often all the way to the main.
