Why is my basement floor drain backing up?
When water comes up through the basement floor drain, the main sewer line is usually blocked between the house and the street. Stop using water upstairs, then call a plumber to clear the main line. If it happens more than once, a camera inspection shows the cause.

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.
Emergencies
Sump pump not working? Causes and fixes
Check power first, then the float: if it's stuck against the pit wall the pump won't start. A pump that runs but doesn't empty the pit often has a frozen or clogged discharge line or a stuck check valve. If the pit is about to overflow, call right away.
