Rotten egg odor in hot water is a common concern here.

The most common fix recommended is to change the sacrificial anode for a
different material. The rationale for doing so is less than detailed,
but some of the sources are official or semiofficial.

The second most common fix recommended is to sterilize the water heater
and/or parts of the system with bleach.

The anode providers usually include a caveat that if any of the old rod
falls off the problem will remain. The bleach fans say you'll probably
have to repeat after a few months.

What I want to know is did anyone try either one and succeed? (and I
mean the odor go away, not just I bought an expensive
anode/bleachinjector/carbon filter and it's a little better)

I have to process the rv heater all the time. I don't leave it on. Normal
treated tap water only has to be set above 120 degrees to keep bacteria
from multiplying. 140 degrees kills them. I do flushing and chlorine
treatment. It's easy to pour chlorine into feed hose to trailer. I dont
anticipate keeping it working, as it's old and rusting around outside
parts. A new tank should have the aluminum rod. Since I have well water,
the water has to be kept more like 130 degrees. Since the tank is small,
there is a tendency to want to keep it hot for reserve.
