I used this to run through our septic line that was stopped up. I pulled plenty of roots and \"debris\" out of it, but it did not clear it. I then went to the other end and had the same results. I ran about 70' in and figured out that the auger was going into the dirt through a break in the line and had to dig it up with the backhoe. The auger went through the blockage and about 20' into the dirt, that is how much power the motor has. The price is the best I have found and the quality is superb. I recommend this snake auger to any home owner.
