It's unlikely you are going to unplug his cheapass home depot toilet with a
3-foot snake. You will want the closet augur as described earlier; it's about a five-foot tubular device with a crank handle on the top end and a bent shaft covered with rubber at the business end. You stand a much better chance with the proper tool and besides you don't have to get face-down in your work like you would with that little closet augur. If all else fails, go to your local hardware-rental company and rent yourself an electric 25-footer; they can help you select the right tool for the job if you splain the situation to them.
