Not much talk about this great machine. Had a nasty back to back bathroom sink stoppage. Tried my top snake with the 5/16 spring head, a couple of straight 5/16 cables with the ends cut off, which is my go to cable and always gets those bad, back to back sinks cleared. Nope. Then tried the K-60 with the 5/8 cable and several cutters and still couldn't clear the line.
After two hours, I bust out the K-3800 with the 13/32 cable(tight fit through the door though) with a half cutter, clears the line fairly easily. Yeah! Just goes to show you, always try everything, and never assume anything. I thought for sure there would be no way that bigger cable would clear the line.
