Hooray for me! My Spartan 100 got a monster workout today. I was able to cleaned out a 4" trap full of self leveling concrete patch. There is no spear/spade tool for this, and I had to use a small greasecutter type tool. Bad news is it took about 3 hours, not just rodding, but pounding the concrete with a pice of 1/2" cooper to break up the big slug in the trap. I must have pulled out 8 knives and a couple pounds of broken glass/china out of the trap. Would a Timberwolf drill and a short section of 1-1/4" with a boring bit be able to get thru a 4" trap? I have one more of these floor drains to cleanout and I don't want to spend that much time on it.
