Crazy thing is, one of the methods plumbers use to install a shutoff valve if they can’t turn off the city point is to freeze the pipe before where the new shutoff valve is to be installed. I always thought that was wild.
Freeze seals are legit. They're insanely common in the nuclear world, so as to minimize the downtime on coolant systems.
