Hi all! This will be my first post here, so I'm hoping for the best. 
I am in the process of replumbing an old house that was built in the 1920s. There were a lot of "hack jobs" done over the years in order to do some bathroom and kitchen remodeling. So, I'm hoping to correct those problems while also modernizing the plumbing systems that are/were once accepted with ABS/PVC and PEX materials.
Here are my questions so far:
1. Is it acceptable to connect multiple vent stacks in an attic to a single roof vent regardless of critical distance? I have been researching this constantly and I have not been able to find a concrete yes/no answer.
2. Is it acceptable to use a 1.5" drain line for a tub/shower and a single lav with proper traps in place? I'm aware that it depends on the code in the area, but it also seems to be something that has changed recently? I'm unclear.
3. Are drum traps obsolete and/or unacceptable when used for tub waste? I'm aware that "S" traps are not acceptable, and "P" traps are preferred. Is there a rule of thumb for "P" trap versus drum trap?
I should mention that I've provided plans and received a permit from the local plumbing authority. I am also planning to hire a certified master plumber to provide his professional opinion before final inspection, but unfortunately my financial situation is forcing me to DIY most of the work.
Thanks in advance.
