I'm sure all submarines have certain processes that can cause leaks if there's an operator error - diving with the hatch open, for example - but are there any that happen as often as toilet flushing?

Per [1], it was a special toilet designed to support flushing at depth (I guess it makes sense that it's a tough problem to solve when the sub is under pressure). I guess previous iterations of U-boats had to surface to flush. It does seem like keeping it in a tank until the next surface would be a better solution though. I mean, they have to surface for other reasons too, right?
