Why does it leak downstairs when a toilet clogs?

Why does this happen even in some very new buildings?? Is it supposed to be like that??

Why does it leak downstairs when a toilet clogs?
When the toilet clogs it overflows and it runs down through the floor. If it%26#039;s not overflowing than there is a leak someplace in the plumbing between the floors. I would make sure the toilet doesn%26#039;t clog...go downstairs or replace the toilet with one that has a larger tank. Some toilets just aren%26#039;t made for large men or large whatever. Kids tend to use too much paper and need to be trained to flush twice or lay off the paper. Good luck.
Reply:The clog is putting pressure on the pipe and exposing another problem, when the water is flowing there is not enough pressure to cause the leak
Reply:These days, the pipe from the toilets lead from the bottom of the toilet, across the roof, then under your house, but in that long maze, a part may be leaking.
Reply:There is a wax type gasket between the base of the toilet and the conveyence pipe it might spent.
