I have a pressure assisted toilet. It hasn't been clogged in the three years we had it. Our medicine cabinet is behind the toilet and I think a bottle or lid must have fallen in the toilet. I plunged my heart out and have tried a small drain snake to no avail. What should I try next?
My brother had that same problem. He picked up a heavy duty snake from Lowe's and it seemed to do the trick. I don't know what it was called but it had a really long snake, so you might want to go there to see what they have. If that doesn't work I would say take the toilet up and see if you can see where it is stuck.
