New plumbing stack

To remove all the old cast iron stack, I had to cut into the wall in the living room, so I thought I should set up some dust extraction (it worked pretty well).

I thought I should have the city residential plumbing inspector come by before I started so he hopefully wouldn't make me redo everything in the basement since it is very much not up to code, and it's how I bought the house.  He was good with it since I'll be ripping it out anyway, and he actually drew me a bunch of diagrams of how to plumb everything, and even included a parts list.  So that was absolutely amazing and about the opposite of what I expected from a city inspector.

He also told me I should plug the stack so stuff doesn't fall down while I'm pulling the old one out and end up clogging it.  And there was a ton of stuff that fell so I'm very glad I did, but I also flushed the toilet while it was plugged and made a mess in the basement...  At least I remembered fast enough that I was able to run into the basement to watch the water come out.

I also decided to just rent a nice soil pipe cutter instead of getting a cheap one or using my sawzall, it worked amazingly and it took less than an hour to get all the old pipe out.

The inside of the pipe that was horizontal for the toilet was disgusting:

A lot of the point of cutting out the old stack was to make it so there wasn't plumbing in the corner of the dining room, which meant moving it to the other side of that wall, and instead of doing funky shit in the basement to tie this into the old stack, I decided to just make it cross over on the first floor, and deal with it later, since I would be redoing stuff regardless.

Before starting on the toilet part upstairs, I decided to reinforce the drop ceiling since it was starting to look like it collapse at any time.

I didn't take many pictures for the toilet, but it was super convenient that there was already a roof vent I could use, so I was able to get it all finished that weekend.
