Can i add all to a 2" pipe?


I'm Currently working on my basement walls and i have a section of pipe in the way. I want to move the Sink/Shower drain out from the concrete wall. I have a 2" Pipe that is currently for the washing machine and wanted to know if i could just have the 1 1/2 pipes come into it and then into the stack. all 3 have there own air intake fyi.

Thanks for any help this is my first post so if i left anything out let me know.

Possibly you can take a pic of the issue. Or some type of sketch.

Not understanding your issue completely.

Size wise, I don't believe a 2" pipe can support all three fixtures (though I don't have the DFU tables in front of me). The harder part is how to connect them correctly, thus Mike's request for a drawing or picture.

Note also that a shower requires a 2" drain.
