Toilet flushes in one particular bathroom always try their best to suck nearby traps dry. Now that I'm renovating that bathroom I want to take the opportunity to install proper venting.
The attached files show the existing configuration, and my (incomplete) proposed changes. My questions are:
1. Is the proposed configuration acceptable to vent both toilet and tub?
2. If so, how would I join the new 1-1/2" (or 2", if required) leg for the vent and tub into the existing 3" horizontal drain without substantially moving the toilet?
3. Is there a better approach than what I'm proposing, even if it's acceptable?
The new vertical vent in the "proposed" photo would go up to the attic, then horizontally about 6 feet to tee into the existing cast iron stack vent.
Plumbing code in my jurisdiction is 2021 UPC.
