Plumbers Okc sent our guys out to do a simple drain cleaning. But simple was not the term we ended up saying. This one turned in to a monster. Customer had over a hundred foot sewer line in their back yard. The guys are running a K 1500 sewer machine with 1 1/4″ cable that is one tough machine. They would run about three feet and their cable would get so full of roots it would not go any more. They would have to pull the cable out and cut all of the roots of and start again. By the time they were finished they had 100 and something feet of cable bent to crap but also a worn out machine.
