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 ...

May need to sanitize using bleach....1/4 cup per 15 gallons.
And it is fine for the RV plumbing.
IF stagnant water was left for long period of time then you may need to do a vinegar soak with 4 heat cycles to clean inside of tank.
4 gallons vinegar/2 gallons water for 6 gallon water heater. Remove Relief Valve, use funnel to pour mixture in, install Relief Valve. Heat vinegar solution thru 4 heat cycles. DON'T use any hot water thru faucets....drain then flush rinse afterwards.
Sulfur smell will be gone
This is basically what I did and it works great. I poured 3 gallons of cleaning vinegar (Walmart, like $2.00 a gallon) in it and let it sit overnight, pulled plug and flushed it out. Two seasons later and still no smell. I was amazed at the amount of calcium deposits etc that came out when the Vinegar was changed.
