I want to use a common drain for a tub and a shower. The most convenient point to tie the two drains together (each has its own trap) is in the center of the bathroom and I would install a single vent connection just before the two drains join. That would necessitate running the vent horizontally about 10 feet to reach a wall and then turning the vent vertical and taking it through the roof. The horizontal portion of the vent would maintain a 1/4" per foot slope. The IRC applies and the installation is in a one story house.
The santee used for the vent connection would be installed with the vent branch in the vertical position.
Is there a limit to how long the horizontal portion of the vent can be?
