As I understand it, code (at least IPC) specifies vents must slope to drain, to prevent condensation from accumulating, but it doesn't care if it slopes toward the fixture drain or toward a vent stack that slopes back to drain, as long as there aren't traps, and it slopes all the way to drain.
To avoid moving some blocking in a wall, I sloped a vent down to the vent stack, away from the fixture drain, thinking this was OK. But, now if I connect to the vent stack with an inverted santee, it will trap the condensation and break my slope. If I connect to the vent stack with the santee in the drain position, then it's not sloping up for the air flow to vent. A vent tee seems the obvious solution, yet nobody around here stocks a vent tee. They talk to me like I'm crazy.
Maybe I am
