Thanks for the reply.
C was the 90 degree elbow in basement for 1st floor toilet. I will put a long sweep elbow there. Should I also put a clean out a the end of this horizontal?
A couple of questions about venting. ...
The 2nd floor shower/sink pipe has a vent before the vertical stack.
I didn't include in diagram as I just located it.
The kitchen sink was direct vented into main soil stack. I think this is against code.
Not sure about venting of 1st floor bathroom fixtures. I'll check them.
On the iron pipe setup there was a vent (iron pipe - the pvc pipe is from basement sink i removed) going in at the basement just above the floor. Pic attached. This vents to roof. I could reconfigure this to vent the kitchen sink and possibly the 1st floor bathroom fixtures.
