I layed awake half the night thinking I was going to have to unbolt the toilet from the floor today. My brother is in the excavating business and said he'd had two lately that acted just like mine was and he couldn't get them unclogged from the outside. I went to the hardware store anyway and bought a rubber outfit that goes on the end of a garden hose. You shove it in the pipe,then turn the water on and it expands to form a seal then uses water pressure to blast out the clog. I stuck it in the cleanout outside,tried it 3 times and BAWOOSH,it cut loose. $32 for it,but well worth not having to get down on a tile floor and take that miserable messy thing out of there.
