    Default need to reattach roof drain leader to sealed standpipe "mystery drains"

    I got dinged by the city for having the leader off a porch roof draining to the sidewalk (not my work, and I understand the safety reasons for the code). Clearly the previous owner disconnected the leader from the sewer system to do this, and I need to reattach it. Lots of question now. What the heck am I looking at here in the basement under the porch? Was the right the drain and the left a cleanout? And for that matter how do these drains attach to the main? There must be a trap, no? Otherwise that floor drain would stink. But what keeps the trap on an leader drain wet? Do they depend on regular NJ rain? But if the leader was removed, shouldn't that trap now be dry even though it doesn't stink? Or did they do something rash like cement it up? That looks like what they did to the cast iron hub on the right.

    So which of these doors do I try, the left capped one that looks like it was oakum packed and lead poured, or the right cemented one?
