I can't accept various opinions regarding why my toilet keeps failing to carry away some very hard (like a brick) stools recently. I flush the toilet and sometimes the "product" fails to disappear down the drain. I purchesed a new plunger and it wasn't strong enough to break up the material. Then I bought a snake and it wouldn't do the job either. Matter of fact, it seemed to me that it was hitting a metal- or steel-like refusal, so no amount of pressure on my part could get beyond this strange barrier. On a couple of occasions the toilet seemed to function but on returning a couple of hours later, there's a little (?) rascal floating in the back of the bowl.
