Basement floor drain backing up?

A basement floor drain backing up with sewage or dirty water is urgent. It often means the main sewer line is blocked—not a simple fixture clog. Stop using water and call if waste is present.

Common signs

• Sewage or dirty water rising from a basement floor drain
• Floor drain overflow when toilets or tubs run
• Sewage smell in the basement
• Multiple upper fixtures slow or backing up at the same time

What to do now

1. Stop using water—avoid flushing, running sinks, or laundry
2. Keep people and pets away from contaminated water
3. Call now if sewage is actively present
4. Send photos of the floor drain and any backup
