Sewage backing up into a tub or floor drain, a sulfur smell in the yard, unusually green or soggy patches over the line's path, or gurgling drains throughout the house point to trouble in the main sewer line, not a single clog. Root intrusion at a joint, a collapsed or bellied section of older clay or cast iron pipe, and grease built up over years are the usual causes, and a camera inspection tells them apart.
Stop running water and avoid flushing anything until the line is checked. If sewage has backed up inside the house, keep people and pets away from the area. Repeated backups after cleaning, standing water in the yard, or a camera showing a collapsed section mean the line needs repair or replacement, not another round of cabling.
