a small plastic cup (the size of a dixie cup and made of fairly thin plastic) got knocked into the toilet mid-flush and went down the drain. i didn’t think musch of it at the time, as it is smaller than most of the stool that normally gets flushed with no problems. the next time i flushed, however, it was slow enough to overflow. after using a toilet auger, i was able to get it to flush, albiet very slowly, and repeated augering has failed to improve the situation. does anyone have any suggestions short of removing the toilet bowl?
