Common Mistakes to Avoid
Using household cleaners with bleach
Never mix bleach with ammonia or other cleaners. This creates toxic chloramine gas that can cause serious lung damage. Stick to the bleach-and-water solution only.
Running the air conditioning
HVAC systems can spread contaminated air throughout your home. Turn off AC and heating until the area is professionally cleaned and inspected.
Keeping wet carpet or padding
Porous materials that contacted sewage should be discarded. They cannot be adequately disinfected and will harbor bacteria and mold.
Delaying the call to your insurance
Most policies have time limits for reporting. Call within 24 hours even if you are not sure about coverage. Document first, then call.
Questions People Ask
- What makes sewage backup different from regular flooding?
- Sewage contains bacteria, viruses, and parasites that cause serious illness. Regular flood water is unpleasant but sewage requires specific safety gear, disinfection methods, and documentation for insurance claims.
- Can I clean up sewage myself?
- Small backups (under 10 square feet) in non-carpeted areas can sometimes be handled safely with proper protection. Anything larger, involving HVAC systems, or with black water contamination requires professionals.
- How long do I have to file an insurance claim?
- Most policies require notification within 24 to 72 hours. Document everything immediately. Take photos before touching anything. Keep all receipts for emergency services and supplies.
- What if I smell sewage but do not see water?
- This could indicate a dry trap, vent pipe issue, or hidden leak. Pour water down unused drains to refill traps. If the smell persists, call a plumber as there may be a broken sewer line.
- Will my homeowner's insurance cover this?
- Standard policies often exclude sewage backup. Check if you have a sewer backup rider. If not, ask your agent about adding coverage. Renters should check their renter's insurance.
Preventing Future Backups
Once the immediate crisis is handled, these steps can reduce the chance of another backup:
- Never pour grease down drains. Collect it in a container and throw it away.
- Only flush toilet paper. Wipes, feminine products, and paper towels cause blockages.
- Have your sewer line inspected every 2 to 3 years, especially if you have large trees near the line.
- Consider installing a backwater valve to prevent sewage from flowing back into your home.
- Know where your sewer cleanout is located and keep it accessible.
