at least once a year, you also need to use a 'flush out' tool to get the sediment from the bottom of the tank flushed out EVEN IF YOU DRAIN it frequently. The tool is easily obtainable at any RV store or Camping World and only costs a few bucks. Just a simple hard plastic tube that is slanted down at the end. You attach it to the end of a water hose and move it back and forth in the 'drain plug' hole. You will be amazed at the GUNK it will wash out of what you THOUGHT was a clean hot water tank.
I only drain mine at the end of the season, but i searched this tool, and i do like the looks and sound of it.
