Flux Corrosion + Galvanic action = Leaks

All of the copper pipes under this home were corroded to the point where a couple leaks had already formed. The main reason for this was that the "plumber" who installed the piping did not remove the excess flux from the solder joints. Flux is extremely acidic and will deteriorate the pipes if left. Compounding the issue were the dissimilar metal hangers used to suspend the pipes from the floor. Using dissimilar metals together will cause galvanic action to occur resulting in more corrosion.
