Drain cables were invented 1935 and the technology is very outdated. Drain line cabling causes damage to your drain lines, does not clean the line the way it should be because it only pokes a hole and gets it flowing it never cleans anything.
Water jetting is the only way to properly clean a drain line. It chops up the clog and sends it down the line leaving your drain lines clean as new! The camera is a tool to see in the line as we are jetting to make absolutely sure every bit of hardened buildup or roots are gone and you have a new pipe again.
