I want to install a washer and need help with the drain.
I currently have two vertical 2" pipes (black pipe) running through the house, but only one vents through the roof. I assume the other connects to the first in the attic (haven't checked though). The one through the roof has a 2nd floor kitchen sink attached to it via horizontal drain with P trap as shown on diagram. The one that connects in the attic (I assume) has a 1st floor horizontal drain with P trap as shown on diagram.
Both pipes continue into the basement and turn horizontal with cleanouts as shown in diagram, connect to eachother and then finally connect to a 4" drain pipe that is leaving the house to sewer.
I have two options as I see it, the first involves tearing out a lot more plaster and lathe, finding the 1st floor vertical drain in the exterior wall, and cutting through some studs with a 2" diameter pipe and P trap to connect to that vertical drain.
The second I like better, but am not sure if it is correctly "vented" or allowed. It involves dropping a 2" drain pipe from the washer into the basement and tieing in to the existing "1st floor kitchen sink" pipe at the cleanout, providing a new clean out afterwards, as shown in 2nd diagram.
Whatever I do, I need to replace the "1st floor kitchen sink" pipe in the basement at the horizontal run, because it's leaking. I was considering replacing all of the 2" black pipe in the basement because it all looks pretty bad along the horizontal runs. View attachment option 1.pdf View attachment option 2.pdf
