In this case, I was running a Spartan 300 with .55 cable and a 2" C cutter down a closet bend, which went into the 3" inlet. It kept jamming up in the side inlet regardless of the direction I ran the drum. Probably didn't help that it was all cast iron too.So what am I missing here? Why doesn't a drop-head on the end of the cable work when cabling down stream from the p-trap of the tub drain? Once the drop-head reaches the inside of the 3" san. tee, it will turn down.
A drop head would likely help, but I didn't have one for that 300, and the 100 wasn't cutting it.
