Stop, don't flush

Every flush and load of laundry adds to what is coming up. Shut off water use immediately.

Stay out of the water

Sewage carries bacteria. Keep kids and pets out and let the plumber and restoration crew handle it.

Clear, camera, repair

The plumber clears the main line, then runs a camera to find the cause: roots, a collapsed section, grease. Hydro jetting handles roots and grease; a broken line needs repair or replacement, often trenchless.

Prevent the next one

A backwater valve stops municipal sewer surges from entering the house. Annual jetting keeps root-prone lines clear.
