Like the list - I humbly submit American Horror Story. Darker and weirder each season. It was much improved by the completely different story line sharing the same cast. Loved it.

Typically in homes of this age the water/sewage was added long after and typically all plumbing will be on a single wet wall. It's highly likely that this additional added structure, typically an add on is the problem child. Jacking only a single section will be far less involved than needed to address the whole structure.
