let me start by saying IT IS NOT CLOGGED.
okay. so i flush a single tissue down the toilet, and it suddenly starts overflowing like mad and won't stop. the water from the tank won't stop going into the bowl, and the water in the bowl isn't going down the drain at all.
there is this big black plastic thing that i propped up and that stopped the water flowing from tank to bowl, but it dint help anything else.
