Roughing in a new bathroom

[mrs falbo]

i'm thinking of putting a 2nd floor bathroom in and would like to know if my venting is good and correct. first, point A, is the 8 foot distance from the toilet to the 2" vent too much. Second, do I need to have a vent to the roof at point B where the 2" shower drain hooks up with the 3" toilet drain? any other glaring problems anyone sees?

No glaring problems really. Make sure the horizontal section of vent is at least 42" above the floor. Make sure you are using wyes (not tees) for connections on the horizontal drains.

Whether that 8' distance is too far or not depends on which code you are using, but the building department will tell you that when you submit the plans for your permit.

thanks for your responses... the horizontal vent will actually be running up over the ceiling, so way over 42". But do wyes need to be used on a dry vent coming off horizontal or just for waste lines and/or wet vents?

Wyes for drainage, tees are ok for dry vents.
