Cleaning is not the same as repair
A cable can open a blockage without fixing a damaged pipe.
Drain cleaning removes a restriction and restores a path for wastewater. It does not automatically repair a pipe that is cracked, separated, collapsed, shifted, or badly deteriorated.
If a line repeatedly plugs in the same area, the recurring problem is useful information. Roots may be entering through a damaged joint, the pipe may have a structural problem, or material may be collecting because the line is no longer functioning normally.
The actual cause has to be determined from the symptoms and, when appropriate, an inspection of the line. A-1 Drain Cleaning does not treat every recurring clog as proof of a broken pipe.
