I winterized my cottage today. Part of that is pumping out the toilets and

But I got to wondering if it really matters; if the water freezes and
expands it has plenty of room to do so without breaking anything. Would it
actually break?


Yes! It is not all that difficult to crack a porcelain toilet. For
example, never pour hot water into a (cold) toilet.
