Raw sewage backing up into your bathtub, shower, or floor drains is one of the most alarming plumbing emergencies a homeowner can face. It’s not just disgusting — it’s a genuine health hazard. Davis Plumbing and Heating Inc. responds to sewage backup emergencies throughout Riverside County, 24 hours a day, 7 days a week.

What Causes a Sewage Backup?

  • Main sewer line blockage — The most common cause. Tree roots, accumulated grease, foreign objects, or a collapsed pipe section blocking the main line forces sewage back into the home through the lowest drains (bathtubs, floor drains).
  • Municipal sewer system backup — Rare, but it does happen. If neighbors are also experiencing backups simultaneously, call your water utility immediately.
  • Flooded sewer clean-out — During heavy rain, ground saturation can push sewer gas and water back up through clean-outs and low drains.
  • Septic system failure — For homes on septic, a backed-up septic tank or failed drain field sends sewage back toward the house.

Immediate Steps When You Have a Sewage Backup

  1. Stop using all water immediately — Don’t flush toilets, run faucets, or use the dishwasher or washing machine. Every gallon you add makes the backup worse.
  2. Evacuate pets and children from the affected area. Sewage contains bacteria, viruses, and parasites — serious health hazards, especially for children and immunocompromised individuals.
  3. Don’t try to use a plunger on a main sewer backup — it can force sewage further into the home through other drain openings.
  4. Ventilate the area if safe to do so — open windows and doors.
  5. Document the damage with photos and video for insurance purposes before any cleanup begins.

Cleanup and Disinfection

Sewage-contaminated areas require professional remediation. Do not attempt to clean up with household products — you need EPA-approved disinfectants, proper PPE, and professional guidance to prevent pathogen spread. Davis Plumbing works with professional restoration companies and can refer you to trusted remediation partners in Riverside County.

Preventing Future Sewage Backups

  • Schedule main sewer line cleaning every 2-3 years, especially in older homes with tree-lined yards
  • Install a backflow prevention valve (sewer check valve) to prevent municipal system backups from entering your home
  • Never flush wipes, paper towels, feminine products, or any non-toilet-paper items
  • Avoid pouring grease or cooking oils down kitchen drains
