what type of PVC would you use in a DWV (drain-waste-vent) pipe like the pipes in my crawl space? cell core PVC?

cell core is for DWV- it will work- the OD is the same as sch 40.

i read that cell core PVC isn't ideal for sewer pipes because it's brittle?

Haven't heard that- we use ABS cell core, residential and commercial. I guess I got a lot of job security ahead of me changing out pipes.....

Sewer is a term that relates to buried lines outside of the building- not inside. For that I use pvc 3034. It is also used by most municipalities I work with.
For building drains- inside the building I use the ABS cell as pvc is not as common here.

for my crawl space DWV pipes, you would use ABS cell core?

there's potentially a 6' section of cast iron beyond foundation wall (pic below). for this sewer section you would use PVC 3034?

Here is what my local inspector would want-

ABS or PVC DWV inside the building and at least 2ft outside- then a cleanout installed with the riser brought up to existing grade. Some towns want a 2-way cleanout.
At that point you can then transition the drain to 3034 or keep it ABS/PVC to connect to what is left in the yard. That connection can be made with a Fernco coupling.

ABS/PVC is ok to run out in the yard- all the way to the city stub- it just costs a little more than 3034- some like it better too. But 3034 is not allowed to be brought into the building's footprint

part of the job is to also replace the cast iron connecting the drains in this section below. my garage has a floor drain which is on the other side of the house separated by a bedroom and breezeway. i wonder if this garage floor drain is also connected? i'm not sure how they did things in the 50s with septic system.

Hard to say but I doubt it. In my area it would have it's own dry well either in the garage floor under the drain- or outside.

i plan on replacing only a 4' section of the cast iron vent on the first floor. my question is: looking at this picture, is there any chance that it could crack during its partial replacement with PVC?

That section should be in good shape as it's been dry most, if not all of it's life.

3 ways to cut it. Use a sawzall, a grinder with a cut off blade, or rent a pair of ratcheting soil pipe cutters.

If you're super lucky, there might be a hub in the wall that can be broken with a few good whacks using a 2lb. hammer.

The upper pipe is extremely heavy, so be sure it's supported well and doesn't come crashing down on you.

Use a cast iron friction clamp on the stack above where your cutting where it is resting on the upper floor.
