Step 4: Sweat
Yes my soldering is ugly, cut me some slack. It was raining and dark, I was drunk and had a huge knot swelling up on my head and I'm no plumber. The solder held so I'm happy. Tomorrow I guess I'm cleaning up this hole in the wall.
Let the pipe fully cool off, to the touch, before kicking the water back on. Don't try and splash any water or anything on it to speed up the process, this might shock your whole mess and result in another leak. Once it's cooled off put pressure back in the pipe by turning on the water main, and open your hose valve and bread bits may or may not shoot out. If you have a little filter in there you can take that out and speed up the process, but the bottom line is the junk trapped in the pipe is bread and will pretty quickly disintegrate and get out of your system.
