Got my K-60 today unpacked it and headed over to a stopped up building sewer call that I got on saturday. Get their have the guy sign my work order and start bringing stuff down and on the second trip he tells me he will help me lift the machine over this lip before the basement steps. But hey I had the 40 lbs K60 no problem nothing to lug up and down steps! Any way I ran the spiral root saw down get 15' bam cable starts binding up pull it back nothing on the tool change the to the straight auger run it down same thing I worked it pretty hard pull it back and found grey clay I had to run it in reverse to get it back. Well about 8 months ago I cleaned a line like this with my bosses K1500 and a large auger so I am thinking I just need to try a little harder. Change to the spade cutter it was worse pulled it back and changed it to the funnel auger and guess what I passed right thru the 15' bad spot like it was not even there now I add a cable and goes right out now I am out 30' I am thinking great all the water ran out told the guy to turn on the L.T. Get the tool back clean figured I washed it off well not so fast look back in the clean out and filing up again. now I tried to run that auger down four more times and could not get any were with it and now every time I had to run it in reverse to get it unstuck I am guessing I just got lucky the one time and the pipe was separated and going right into the clay and boring a hole and hanging up. and the last time down I pulled back little stones showed the guy packed up my stuff printed the invoice up got paid cash and I told him I would need to come back and dig up the line measured it seven feet down going to need a box. To you guys that use jetters would that be another option to open this up or just a temp fix till he can get some real money for a replacement job, or will it not work at all if so what would you use for a 4" to 6" building sewer what G.P.M. p.s.i etc. Maybe I can rent one and open it up for the guy thanks guys Oh yea and the K-60 kicks A$$ just not clay and separated pipes.
