I looked at a 5 year old house. The water heater has an expansion tank on it. The pipes are copper. I noticed in the bath sinks that the hot water ran rust-colored for a bit before clearing up. I don’t recall seeing that in the kitchen sink. Anyone know what could be causing that? Does it have anything to do with the expansion tank?
