A sewer backup in your basement isn’t just gross—it’s dangerous, stressful, and costly if not handled fast. Unfortunately, Dayton homeowners know this issue all too well, especially after heavy rain or aging pipe problems.
Before you panic or start pouring bleach everywhere, here’s a step-by-step guide to safely fixing a basement sewer backup, what causes it, and how to prevent it next time.
Step 1: Stop Using Water Immediately
Turn off all faucets, toilets, dishwashers, and laundry machines. Any water you use can worsen the backup and flood your basement further.
If safe, also shut off power to the affected area. Sewage + electricity is never a good mix.
Step 2: Keep Everyone Out of the Area
Sewage carries harmful bacteria, viruses, and parasites. Keep children and pets away. Avoid walking through the water—especially if you have open cuts or sores. If you must enter, wear gloves, rubber boots, and a mask.
Step 3: Identify the Severity
Ask yourself:
- Is the water clear, gray, or black?
- Is it rising or holding steady?
- Is it only in one drain or all lower-level drains?
If there’s black water or more than a few inches of flooding, it’s time to call a professional. This isn’t just a clogged drain—it’s likely a main sewer line issue.
Step 4: Call a Local Sewer Backup Expert
Dayton has older homes with aging sewer systems, tree root issues, and combined storm/sewer lines in some areas. It’s important to contact a local sewer repair company that understands how to fix backups specific to this region.
Dayton Sewer Repair specializes in main line inspections, hydrojet cleaning, and trenchless pipe replacement if needed.
If you’re unsure whether it’s a city or homeowner issue, the City of Dayton Sewer & Stormwater Division provides helpful info on who’s responsible.
Step 5: Start Cleanup (or Call a Crew)
Minor backups can be handled with proper protection:
- Use a wet/dry shop vacuum
- Disinfect all surfaces
- Remove any soaked items (carpets, boxes, drywall)
But for anything involving raw sewage or standing blackwater, don’t risk it—call a certified cleanup crew.
Step 6: Schedule a Video Inspection
Once the immediate issue is handled, have your sewer line inspected with a camera. This reveals the cause—whether it’s a tree root, grease blockage, pipe collapse, or something else.
