My cousin has a home in the mountains. There was a recent cold snap where it got below zero degrees for several days. Yep, one of his copper pipes blew out in his garage. He called a local plumber and they said there are at least 1000 homes with the same problem, and his wait time is close to two months!
I went up today and I fixed the broken line in about 5 minutes. I even received a new map gas torch with auto ignite, new solder, emery cloth, flux, DeWalt saw blades, a mini-tubing cutter, etc for my trouble. Of course, I will purchase a new plumbing bag for this equipment, so the next time he calls, I'll be ready.
