I have never drained a water heater. Most people don't. I would be concerned that the valve will start to leak because of sediment clogging it up. Also, I don't think that opening the drain valve is an efficient way to remove sediment unless you do it every month or so. If you have years of sediment built up, I believe it will mostly be caked onto the bottom of the tank, and will stay in the tank when you open the drain valve.
