Most systems today, have an air bladder in the pressure tank . However, rust in a system with air is more likely to be coming from steel components than dissolved iron in the well water. Someone more familiar with potable water chemistry should be able to determine the source. I think time is necessary ( such as hours) to oxidize soluble ferrous iron. | |

That is, it was always there but it wasn't noticeable without air in the system? | |
