    Default Basement rough in - does this look OK?

    I'm hoping to keep this simple and I think the drawing has all the info. The 2" shower vent will continue out the roof and the 1-1/2" vents from the lav and laundry will tie together 5' up, and pick up the 2" above the ceiling. I couldn't find a long turn 90 for the closet bend fitting in the drawing but I will either use one or use two 45s.

    It would fly under the IPC but many localaties still require a vent for the toilet line

    I would forget the "long turn 90, or two 45s" and use a hub 4x3 closet bend. It is the ONLY way I install my toilet riser pipes.

    Default Interesting

    Thanks very much for the input. I guess I'll have to run it by the inspector. I'm located in Ontario and I'm not sure what our code is. I guess it's close enough to not get laughed or yelled at!

    That 4x3 fitting is cool - I've never seen one of those before. I can see how well they would work but is that the only time in DWV plumbing you're allowed to in effect reduce the pipe size ??

    If I need to vent the closet, I would change the shower vent to 1-1/2 and vent the closet with 2" correct? At that point could I connect the other vents from the group and run to the roof with 2" ?

    It is the only place where the code allows the reduction.

    You are fine under the Canadian national code, the toilet is wet vented and is 2".

    Jerome - thank you very much - the inspector agrees! Good to go. He mentioned something about 5' being good. I imagine it's that the shower drain/wet vent connects to the 3" horizontal run within 5' of the toilet flange.

    Edit - from planning to completion!
