So, this time around, I was careful to run every pipe through the exact center of 2x6 walls. The nails simply can't reach the pipe. Well, except for an area of about 6 square inches where the pipe had to go around the sewer line coming down the wall. That's 6 square inches out of 1600 square feet That puts the odds at 1:38,400 for each nail fired. So, shoot enough nails and get in rush mode before the snowstorm hits, what do you get?
Pssshhhh.
Nuts.
At least it was a pretty easy fix this time.
I was able to get a special pipe cutter in there---it clips around the pipe like a knob and you just keep turning it until it cuts the pipe. I cut on either side of the hole . A few feet to the left of the fix, the pipe turns and goes way up the wall so I had plenty movement to work with. Normally you have to cut out a section and put in a new section with a coupling at each end. They do make a nifty 5/8" pipe that you can use as a really long slip coupling. I bought one for my repair kit.
Construction projects have been burned to the ground by plumbing fixes. Hot fire in enclosed wooden boxes, with all the water shut off. Go figure. I tood a scrap of the cemetitious soffit material and used it as a backer to protect the wood----worked great. It's now part of the same repair kit.
Here's the repair and the section I had to cut out. I couldn't have hit that thing more square.

There's not too much exterior siding left to do. I will have to move the scaffolding over to this side to finish it off. The yellow board over the fire sprinkler panel is where I hit the pipe, which is why work stopped there. To the right, that's as high as I can reach without the scaffold
