We don't like removing and re-installing the anode rod - other than at the end of the season. So, instead, we use the outside shower - running only the HOT water while we're filling the fresh water tank. We fill a 5G bucket with the 'old' water from the HW tank while the fresh is coming in. I know it's not getting all the 'old' water out, but it gets most of it. Since we started that process, we've avoided the 'smelly sulpher' water from the HOT side.
