Despite various interruptions, I'm continuing to make progress. I just need to run a wire to the subpanel and put down the shower liner, and I'm ready for the next inspection.
The most recent task was connecting the new DWV (drain waste vent, aka sewer) pipes to the existing ones. The new ones are ABS plastic, but the existing ones are cast-iron pipe. A quick attempt with the Sawzall revealed that wasn't going to work to cut the cast-iron pipe, so I rented a snap cutter that's designed for it. I'd never used one before, but it turned out to be very easy. Put the chain around the pipe, tighten a little and score the surface, then tighten the rest of the way and *snap*. It took me less than 5 minutes for the two cuts needed, significantly less than the time to and from the rental place. And it wasn't even a stinky job.
And even though I sweated around 25 joints for the plumbing (mostly for the shower, since it has extra bends to go around the higher foundation at the side of the addition) with no problems, I don't think I'll be running out to become a plumber any time soon. Too many of the tasks that go with the job are stinky, even if the pay is good.
Barring an unusual number of interruptions, I'll get the next inspection this week. After that it's insulation, drywall, flooring, trim, paint and I'm done! OK, so that's still a lot of work. And when I finish that I get to start on the kitchen...ah, well. One step at a time.
