Diagram/vent 2

[FromParis]

Hello again guys.
I have been checking what I can do based on the comments I received.
here is the new diagram. i hope it s easier to understand...You can guess that I cannot connect the shower directly to the drain...



I have 2 questions:

1- Is revent 3 really needed?
2- I put the shower as wet vented. But I think there is too much distance between the drain and the vent. Would it be OK if the vent is put at the intersection of the lavatories and shower drain? otherwise, I can put a vent #4.

Thank you,

Olivier

VEnt #3 is cosmetic and serves no functional purpose. The problem with the tub is its distance from the drain connection, and it makes no difference where the vent is on that pipe, it will not make the shower "legal".

Thank you HJ for the answer. that was I thought...

So, here are my final 2 propositions: Does it work and it is better with revent 3 or 3 bis?
This is probably my last attempt as I am out of ideas. Problem is it is hard to find a good plumber in Calgary (jobs and contracts everywhere!! good for them though...).

I really do appreciate your help.
