The short answer
Common Causes of Sewage Backup
A clog in the vertical drain pipe that connects your bathtub to the main sewer line is a frequent cause. Hair, soap scum, and small objects can build up over time and eventually block the flow. When water from other fixtures pushes against that blockage, the sewage has nowhere to go but up through your tub.
A blockage in the main sewer line outside your home can also cause backups. Tree roots, grease, or a collapsed pipe can stop the flow for your whole house. If toilets and sinks in other rooms also drain slowly, the problem is likely in the main line rather than just your tub.
A blocked vent pipe on your roof can create a vacuum that prevents wastewater from flowing down. Without proper venting, pressure builds in the drain system and forces sewage back up. A full or failing septic tank can have the same effect, pushing waste upward into your tub.
- Slow drains in multiple fixtures
- Gurgling sounds from the tub drain
- Foul odors near the tub
- Water level in the tub rising on its own
- Sewage appearing after heavy rain
- Toilets that flush with difficulty
Health Risks of Raw Sewage
Raw sewage contains bacteria, viruses, and parasites that can make you sick. Contact with contaminated water can cause skin infections, gastrointestinal illness, and respiratory problems. If you feel unwell after exposure, see a doctor.
Do not enter a room with standing sewage without protection. Wear rubber boots, gloves, and a mask if you must go near it. Keep children and pets away from the affected area. Open windows for ventilation, but avoid using fans that could spread airborne contaminants.
Immediate Steps to Take
Stop using all water in your home. Flushing toilets, running sinks, or using the washing machine can push more sewage into the tub and worsen the backup. Turn off the water supply to the affected fixtures if you can, and avoid touching the sewage.
Call a plumber or a water damage professional right away. They can identify the source of the blockage and clear it. Keep the area blocked off and do not attempt to plunge or snake the drain yourself, as that can force sewage into other parts of your home.
Cleanup and Repair Considerations
Cleaning up raw sewage is not a do-it-yourself job. The porous surfaces in your bathroom, like drywall, flooring, and grout, can absorb contaminants and need to be removed and replaced. Local water damage pros have the equipment to dry the area and dispose of contaminated materials safely.
The cost of cleanup depends on the extent of the backup, the materials affected, and the labor involved. It often ranges from a few hundred to several thousand dollars. Your insurance policy may cover some of the damage, but policies vary, and your insurer decides what is covered.
- Turn off the water supply to the tub if you know where the shutoff valve is
- Remove any items from the floor that can be laundered or discarded
- Take photos of the damage for your records
- Avoid using bleach or other household cleaners on sewage, as they can create toxic fumes
- Keep the room closed and ventilated to reduce odor
Preventing Future Backups
Regular maintenance can reduce the risk of future backups. Avoid flushing wipes, paper towels, or grease down any drain. Use a drain strainer in the tub to catch hair, and clean the drain regularly with a mixture of baking soda and vinegar.
If you live in Tulsa, keep your shutoff valve location written down. Have a plumber inspect your main sewer line every few years, especially if you have trees near the line. A backwater valve can be installed to prevent sewage from entering your home, but that requires a professional assessment.

Can I fix a sewage backup myself?
You can try to clear a minor clog with a plunger or a drain snake, but raw sewage is hazardous. If the backup is extensive or involves the main sewer line, call a professional. Attempting to fix it yourself could spread contamination and cause more damage.
How long does sewage cleanup take?
The duration depends on the size of the affected area and the extent of contamination. A small bathroom may take a few days, while a larger area could take over a week. The pros will need to dry the space and may need to remove drywall and flooring.
Will my insurance cover sewage backup damage?
Policies vary, and your insurer decides what is covered. Some policies include sewage backup coverage, but it is often a separate rider. Review your policy and contact your insurance company to ask about your specific situation. Take photos and document the damage for your claim.
