We used to fix our drainage problem between kitchen sink and the main pipe, about 25 ft, 2-inches pipe. Because of the 2- inches pipe, we only could use the two smaller bits, and they fixed our problem.
It works great. I bought it because my sewer line was blocked it cleaned it out great. Turns out it was the town sewer that was the problem. It paid for itself, I cleaned 14 lines on my block at $100 a pop.
I bought this because I was having some plumbing issues and didn't want to keep calling a plumber. Works great every time, and has definitely saved me a lot of hassle! I would definitely recommend this product!
Received it Friday, used it Saturday. Cable is more flexible than a similar model that I used. That did allow me to go down a drain that I couldn't with the other auger. Worked good for the money. So far, so good.
