Atwood Water Heater Rotten Egg Smell
I completely drained and flushed our Atwood water heater recently because I noticed that rotten egg smell. We are now on the road and the smell is back. Never happened before. Did I not flush it well ...

It could be sulfur bacteria (not dangerous, only stinky) which you picked up with a load of water (not uncommon with well sources), and which changes sulphates in the water to "rotten egg" gas. Disinfect it. Chlorine bleach is most available/cheapest (put a cup in your tank, pump it into the heater, let it sit overnight), but not particularly good for the rest of the water system. If yours has an anode rod (not all Atwoods do), replace it first - the magnesium in them makes it worse, and used ones have lots of crevices for the bacteria to live in.
Iodophor is a better alternative but not usually something you can pick up at the local store, unless there's a homebrew beer store around.
