hello, ive been in the hvac and oil heating field for about 7 year. for the past 2 year ive been a plumbing apprentice. I do a lot of maintenance for 10 motels on the night and weekends. they been asking me to do the drain cleaning for them for a while, use the drain machine at work quit a bit. At work we use drum machine, but ive reading a lot on the ridgid forum and i like the K-60. I order one a week ago and i have it now. i got the 7/8 open wind cable kit to start with. was wonder if there was any trick to it? and wont to get the 5/8 cable for it to do 1 1/4 to 1 1/2 pipe size. what would be the best cable type to go with. also I hear from some people it better to make your own cable by getting 5/8 by 100' cable and cutting it up any thought on that?
