On top of that you would need to use distilled water only. Otherwise mineral build up will occur at some point. Either at the injectors, or the valves/exhaust ports.

You are going to have to cut the drywall to get to the joint. Otherwise that is a straight forward repair. Shut the water off, cut the sheet rock, cut the joint , sweat the new joint, pressure test, redo drywall. done!
I guess the worst thing about my cousins situation is that he was not the one who killed the two people. He was with the kid during the robbery, and the 16 yo guy shot the two people. The kid that shot the people got Life with the possibility of parole in 2017. My cousin who was an adult gets the death penalty. I am not saying my cousin should get out of jail but I am not sure he deserves the sentence he got when the trigger man gets life.
So in his case you have someone going to die, even though they did not do the killing.
