I found the city website that shows the city sewer lines in the street. Then I found a way to make it show the individual houses' connections. Not sure how reliable this info is, I notice many houses have no connection shown, I imagine there are no records from when these houses were built 100 years ago (105 for mine) so the info gets updated only as work is reported to the city. But anyway it shows my house and my neighbor's house as each being connected directly, and separately from each other, to the city line. Kind of wish I'd found this website before, it might have made some of the troubleshooting more efficient.
