Speaking of this, why does the tap water smell so bad on many of the DCI RJs? Three of the last four times I washed my hands, they smelled stale for the rest of the day (like wet washcloths left next to the sink for a few days).

Are the ground crews on our replacement aircraft cutting corners and not flushing out the tanks? I've accepted that they will be flying most Delta pax in the future, so I thought for my parents nonrevving, etc they might as well at least have clean water.
