oops you are correct.
I was told to turn off water heater, then run a faucet so all the hot water is gone.
Turn off water source.
To still give the water heater some time to cool down.
Open and remove the anode rod to let water drain out. Was told if water dribbled that means sediment or general gunk is blocking it and carefully use a wire coat hanger or some such thing to clear.
I was told just to use a water hose to flush it, but looking at the head of the anode rod, seems I'd need something smaller to get water in without it flooding and running back out for the most part, thus my question if there was an attachment needed. If so, means another online search and to order.
I'm still puzzled/concerned about the mention of the heating elements. As long as I let the water heater cool they should be ok shouldn't they?
I think I'll take a picture and post of my particular unit and highlight the areas I have questions about. Any Suburban owners out there..tips for flushing would be appreciated.
Perhaps I'm blowing a simple procedure out of proportion, but I get differing suggestions as I've said. (nope, no manual)
