Hi. I am a novice. I have a full shower with a draining problem. In the past, I have remove the grate and used a hanger to clean it out. This time my hanger does not work. I have tried chemicals and that has no effect. I have the K-Spin hand snake and I cannot find the direction of the pipe. It goes down about 8-10 inches and spots. I feel around with the hangar to see if its going left, right, up, or down. Doesn't appear to go anywhere. Like a Dead-end. Is there a trap or something? Like I said. I don't know what I'm doing. Any suggestions?
