The short answer
Common Causes
A blockage in the main sewer line is the most frequent reason. Grease, hair, soap scum, or flushed items can build up and block the pipe, causing waste to flow back through the lowest drain, which is often the shower. Tree roots can also invade underground pipes and cause clogs.
In some cases, the backup comes from the municipal sewer system being overwhelmed by stormwater, especially in a humid subtropical climate with heavy spring rains. If the problem occurs during or after a storm, the issue may be outside your home. If it happens regularly, the cause is likely a persistent clog in your home's plumbing.
Health and Safety
Sewage contains harmful bacteria, viruses, and other pathogens. Avoid direct contact with the wastewater. Keep children and pets away from the affected area. If you feel unwell after exposure, see a doctor.
Open windows to ventilate the space, but do not run fans that could spread contaminants into other rooms. Turn off the water supply to the shower if possible to stop the flow. Wear gloves, boots, and a mask if you need to be near the spill. Do not attempt to clean it up yourself without proper protection.
- Turn off the water to the shower if you can find the shutoff valve.
- Keep people and pets out of the bathroom.
- Open windows for ventilation.
- Wear rubber gloves and a mask if you must enter the area.
- Do not use the shower or any other drains until the issue is resolved.
What to Do First
Stop using all water in your home, including sinks, toilets, and showers. Continued use can worsen the backup and spread sewage further. If you have a cleanout access point on your main sewer line, you can check for a blockage there, but do not attempt to clear it yourself.
Contact your local water damage pros to handle the cleanup and sanitation. They have the equipment and training to safely remove sewage and disinfect the area. Also, call a plumber to inspect and clear the main drain line to prevent future backups.
If you live in Rockwall, keep your shutoff valve location written down so you can act quickly if this happens again.
Why Professional Help Matters
Sewage cleanup is not a DIY job. The pros use specialized equipment to extract wastewater, remove contaminated materials, and sanitize surfaces to eliminate health hazards. They also handle disposal of contaminated waste properly.
Professional drying and dehumidification help prevent mold growth, which can start within 24 to 48 hours. They can also inspect for hidden moisture in walls and floors. This thorough approach reduces the risk of long-term damage and health issues.
A plumber is the right person to clear the actual blockage. They can use augers or hydro-jetting to remove clogs and assess the condition of your pipes.
Preventing Future Backups
Avoid flushing anything other than toilet paper and human waste. Do not pour grease or oil down any drain. Use a drain strainer to catch hair in the shower. Regularly clean your drains with a mixture of baking soda and vinegar to help prevent buildup.
Consider having your sewer line inspected with a camera to check for root intrusion or pipe damage. This is especially useful if you have older plumbing or trees near your sewer line. If roots are an issue, a plumber can recommend treatment options.
During heavy rains, be mindful of the load on the municipal system. If you notice backups only during storms, contact your local utility to report the issue.
- Install drain strainers in all shower and sink drains.
- Never flush wipes, paper towels, or feminine products.
- Pour hot water down drains weekly to clear grease.
- Have your sewer line inspected periodically.
- Know where your main shutoff valve is located.

Is sewage backup a health hazard?
Yes, raw sewage contains harmful pathogens that can cause serious illness. Avoid contact with the wastewater and do not let it dry, as bacteria can become airborne. See a doctor if you feel unwell after exposure.
Can I fix the clog myself?
You might clear a minor clog with a plunger or a drain snake, but if sewage is backing up, the blockage is often in the main sewer line, which requires professional equipment. Attempting to clean it yourself can spread contamination and cause further damage.
Will my insurance cover the damage?
Policies vary, and your insurer decides what is covered. Some home insurance policies cover sewage backup, but often as an add-on endorsement. Check your policy and contact your insurance company to discuss your specific situation.
