Yes, brief and superficial, but my reference was to this part of the article...
Repairing
Quote:
• The main problem with black iron pipe
--especially in the home--is leakage at connector spots.
It requires a lot of work to fix these leaks,
which is why many people no longer use black iron pipes.
Steel pipes do not have that problem because it is most often welded.
However, it is more expensive than black iron pipes or PVC.
