Well, it looks like I'm going to replace everything with new. I'm looking at coming across with 2", popping up thru the floor with 2" for a washing machine, then popping up with 1 1/2" for the back to back kicthen and bathroom sink(which would vent with 1 1/2"), and ending with the pt rap for the tub and shower.
another thing I was looking at was popping thru the floor with a 2" for the sinks and have the washing machine tie into to that.
I'll try to get a picture up. I see alot of people have looked at this thread but no reponses, so maybe that will help.
