Common Sewage Backup Scenarios

Stop Using All Water

Every flush and drain use adds to the backup. Stop all water usage in the house immediately until the blockage is cleared.

Avoid Contact

Raw sewage contains bacteria, viruses, and parasites. Don't wade through it or touch it without protective gear. Keep children and pets away.

Ventilate the Area

Open windows and doors near the affected area. Sewage gases (methane, hydrogen sulfide) are hazardous in enclosed spaces.

Call a Plumber Immediately

Sewage backup is a true emergency. Most emergency plumbers can respond within 30-60 minutes. Do NOT attempt to clear a main sewer line yourself.

Frequently Asked Questions

What causes sewage to back up?
Common causes: main sewer line clog (tree roots, grease, debris), collapsed or bellied sewer pipe, city sewer main backup, or heavy rainfall overwhelming combined sewer systems. In San Francisco, tree root intrusion is one of the most common causes.
Is sewage backup dangerous?
Yes — raw sewage is a serious health hazard containing bacteria (E. coli, salmonella), viruses, and parasites. Do not touch sewage without protective gear. After cleanup, the area needs professional sanitization to prevent illness and mold.
How much does sewage backup repair cost in San Francisco?
Emergency sewer line clearing: $200-$800. If the backup revealed a broken or collapsed sewer line, repair costs $1,500-$10,000+ depending on the method and extent. Professional cleanup and sanitization adds $1,000-$5,000 for significant backups.
Does insurance cover sewage backup in CA?
Standard homeowners insurance in CA typically does NOT cover sewer backup damage. You need a separate sewer backup endorsement ($40-$100/year). If you don't have it, you'll pay for cleanup and repair out of pocket. Check your policy now — before the next incident.
