I just remembered why: there’s a place where you look and are told, this is where everything from the sewer washes out. I held onto that it must be a puzzle, needing to make something flow through the sewer to retrieve something else.

I might have imagined it, but I could swear there was a single valve where the chracter goes “hmmm, this one looks different!” or something. That confused the hell out of me.
