Main stack

could anyone help with this please....

basement floor - bathroom group
main floor - toilet (stub out) /sink and kitchen sink
first floor - bathroom group
proposed second floor addition - bathroom group --- where the vent stack is offset now (in the drawing) it will be cut and go straight...i just did it this way for now because of the icy conditions/ladder use etc plus i already had a hole in the roof there.

any and all feedback welcome

thanks np

now tied in the vent to the stack - any feedback? thanks NP

anyone? any advice at all?

What I see looks fine.

Thanks for your input Terry (as always) sorry for not reporting back on my previous posts. - I have a structural inspection tomorrow and he will be looking at the stack too. What I have done just looked really messy to me with all the reducing.

Would you have done it differently? I dont have access to the stack below the 4" WYE so this is the only way my newb brain could get around it. I purchased a book 'venting systems guide for plumbing'...ISBN 978 897498-20-0 - PLEASE DELETE REF IF INAPROPRIATE.


anyhow, feel better now feedback has been given.

Thanks as always Terry --- always an invaluble site
