Im trying to free up a clog in my kitchen sink and when I try to put the snake down the pipe it goes in about 4ft and then just stops, and don't believe this is where the clog is and have a feeling that there is a tight angle Im just getting it past. And I've tried pushing it in as I spin the snake and have tried doing it both clockwise and counter clockwise but with no luck and just wondering if you might know of any other tricks to go down? Thanks
