I'd like to get advice on a plumbing rehab in an old house with back to back bathrooms and laundry. There is a 1.5 inch and a 2 inch vent leaving the house. The clay pipe to the street sewer out in the yard is 3", but the ABS inside is 4" and must transition at some point underground before I owned the house. This has not been a problem.
I'd love to add a second bath without adding another 2" vent through the roof but I'm pretty sure I'm going to need to add one 2 inch (orange) vent above bathroom 2. The shower #2 is closer to the original 2 inch vent (blue) and I'd like to use that. I'd like to use the blue vent for the Washer and a utility sink too on the same wall as the bathroom. Any advice would be appreciated.
I fall under the California Plumbing code based on UPC (2019).
