I knew this, but had a harsh realization once. I was moving out of a place, and flushing down the things that were flushable to save garbage runs.
One such thing was a jar of mini-pickles. The next day, I realized why that was a problem. They probably rehydrated in the pipes back to their originalish size. That toilet didn't flush properly again for a while.
