A little more minor progress on the house fire situation

The stuff I am using uses either a crimp ring or what is called a pinch clamp. The crimps are hard for me, as i don't have a power tool, and 3/4 is nearly impossible for me to crimp without having the pieces on a bench where I can put my weight on the crimpers
I've had a lot of success with those shark bite fittings in tight spaces. They make them for pex. They cost more though. The trick is there's like two steps. When you first push the pex into the fitting, it'll feel like it seated, but push it again and it'll actually seat all the way.
