Most people don't do any maintenance on a tank type water heater. You can flush out a tank type water heater, but there is always a risk that you will create a leak in the drain valve. The Rheem manual "suggests" that you drain a small amount of water every month or so but doesn't recommend a complete flushing. I have never done any maintenance on a tank water heater, but some people do.
