Hoping to get some advice on my DWV setup for a 8'x14' 2-story addition I have been building. I am the homeowner and am doing all the work myself. I'd say I'm about 90% decided on my DWV setup, but need to get some feedback for the last 10%.
Below is a rough sketch of my layout. Drains will be in a crawl space. 1st floor bathroom, 2nd floor laundry
My biggest dilemma is determining my proper vent layout for the1sr floor bathroom. I can’t dry vent each fixture separately due to framing and other limitations. I’ve known from the beginning I’d need to figure out a wet venting option. I’ve been back and forth in my head and at this point I don’t think I know what is up and what is down. Where does the vent need to attach to the 3” horizontal? Any feedback or other options are appreciated.
**Just to note: I’ve discussed a prior plan with my code inspector that I know was not the correct way to do and he approved it. So I’m not relying on him to confirm. He’s already passed my inspection just based on our discussion.
