Sewage backup in the house: what to do
Updated
Short answer
Stop using all plumbing, keep people and pets away, and avoid touching the water. A plumber clears the line or a septic company pumps the tank; a restoration company removes contaminated materials, disinfects and dries. Check your policy for a sewer backup endorsement.

Right away
- Stop running water, flushing toilets, and using the washer and dishwasher.
- Keep children and pets out of the area.
- Turn off power to affected rooms if you can do it safely from a dry spot.
- Don't touch the water without gloves and boots.
- Photograph from a distance.
Find and fix the cause
A plumber can snake or camera the sewer line to find roots, grease, wipes or a broken pipe. For homes on septic, a pumping company checks the tank and field; heavy monsoon rain can saturate leach fields and cause backups.
What cleanup involves
- Extraction of water and solids
- Removal of carpet, pad, lower drywall and insulation that were touched
- Cleaning and disinfecting hard surfaces and framing
- Drying and verification before rebuild
