I've had a stubborn clog for a while and used google to find some ideas on how to fix it (not a smart idea..) Well someone said to take off the over flow cover and stick a hanger with a small hook on the end down the hole and try to pull out what might be causing the clog.. so I took the cover off and when I tried to pull the hanger back up.. IT WAS STUCK! It's hooked onto something about three or four inches down and I can't get to it! Help please
