There are a couple of nursing homes down here that have had pipe failure problems in the attic and both have been in salt air environments. Pin hole leaks as you describe. This was sch 10, however and there may have been pitching problems as well. I never did a full replacement on either because they didn't like the price. I don't remember if the air source from the compressor was in a conditioned space or just a basement.
