Hello,
I am currently remodeling a bathroom in a small home I just purchased out in the country. I don't think they are very strict as far as plumbing code here but I would like to do things the correct way. It is in Michigan so will be based off IPC.
First picture is the current DWV set up. There is only the one bathroom group in the house and also the kitchen sink, no other plumbing fixtures in the house. I feel like they have it vented a bit odd with the 4" pipe going up through the roof and not inside of the wall framing, so that has got to go.
The second picture is the proposed new layout looking at the setup from down in the crawl space. The lav is being moved to the opposite side of the bathroom (behind me in the picture), the toilet is directly above the main stack, and the bathtub drain will be adjacent to the toilet to the left. I would like to get rid of the 4" vent and horizontal arm coming off of the main stack to the left.
The third picture is more of a side view of the whole bathroom from top to bottom. I'd basically like to get it where I can get rid of that original 4" vent coming off the horizontal pipe from the main stack. Instead I would vent it up through the dry vent coming up off the lav and meeting up to the existing 4" vent going up through the roof. Then wet vent 2" down from the lav, picking up the bathtub, and WC which is basically directly over the main stack going out to the septic tank. I don't know if the kitchen sink can stay the way it is, it is not vented any other way currently. Was thinking to just add an AAV for the kitchen sink vent.
Please let me know if this looks like it would work or what would need to be corrected. Any and all help is greatly appreciated as I am a newbie on here. Thank you.
