Onion/egg smell from hot water.
Not sure if this is the right forum, but I could use your help. I got a bad smell when running the hot water. This is what I have done so far. Drain fresh water and and hot water tank. Filled wi...

It can also be caused by water with some sulfur content.
The following is from the Atwood service manual:
"1. Turn off your main water supply. Drain your water
heater tank. Reinstall drain plug. Remove the
pressure-temperature relief valve. With a funnel
use 4 parts white vinegar to two parts water. (In a
6 gallon tank that would be 4 gallons vinegar to 2
gallons water).
2. Cycle the water heater, letting it run under normal
operation 4-5 times. At no time do you remove the
vinegar from the tank Once this has been
completed, remove the drain plug and drain the
water heater.
3. After thoroughly draining the tank, to remove the
sediment, flush the water heater.
If you elect to use air pressure, it may be applied
either through the inlet or outlet on the rear of the
tank or applied through the pressure-temperature
relief valve. Remove the pressure-temperature
relief valve and insert your air pressure through
the pressure-temperature relief valve coupling. In
either case, with the drain valve open, the air
pressure will force the remaining water out of the
unit.
If air pressure is unavailable, your unit can be
flushed with fresh water. Fresh water should be
pumped into the tank either with the onboard
pump or external water pressure. External
pressure may be hosed into the unit either
through the inlet or outlet found on the rear of the
tank or the pressure-temperature relief valve
coupling located on the front of the unit.
Continue this flushing process for approximately
five minutes allowing ample time for the fresh
water to agitate the stagnant water on the
bottom of the tank and forcing the deposits
through the drain opening.
4. Upon completion of the steps above, replace the
drain plug and the pressure-temperature relief
valve.
5. Refill tank with fresh water that contains no
sulphur."
