Per ATWOOD:
1. Turn off your main water supply. Drain you 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.


Is it time for your medication or mine?

DW has corrected my post about the vinegar mixture. I said 2 water to 1 vinegar. She said it was 4 parts water to 1 vinegar. Sorry for the confusion.

The only time I had egg smell from the hot water. I turned the water pump off Drained the hot water tank. Funnel poured some bleach into the drain hole. Put the drain plug back in. Turned on the water pump. Opened the relief valve till water came out. Shut off water pump. Waited 24 hours and then drained the tank. Ran the pump a bit to flush the bottom of the tank. Turned pump off. Put drain plug back in. Turned on the water pump. Turned on the hot water tap in the kitchen and waited for water to come out of it, done.

Oh it had a slight chlorine smell at first. About the same as when you finish de-winterizing just the pipes. The smell never came back.

I've seen home water heaters where the hot water smelled like rotten eggs. When the anode rod is removed the rotten smell goes away.


Atwood RV water heaters have aluminum tanks and no anode rod (the OP says his is an Atwood).

Suburban RV water heaters have steel tanks and DO have anode rods. I think the Atwood water heater is by far, more popular with the RV manufacturers than the Suburban.
