Sewage backup is Category 3 blackwater, which means it carries real health risk and requires a completely different protocol than a clean-water leak. This is one water damage situation where calling a trained crew immediately matters more than trying to handle it yourself.
Containment goes up immediately to keep contaminated water from spreading to unaffected areas of the property.
