Does anyone drain the HOT water heater . . . .

. . . . when not using the trailer? The Shop Foreman at the dealership suggested that I drain the water heater whenever the trailer was going to set unused for more than a couple of days. His reasoning was that the "crud" build up from hard water deposits would be flushed out more often and could extend the life of the heater. I've not done that before, usually waiting 'til I winterized in the Fall, with any of the other units we've had. I replace the anode rod every 2 or 3 years but other than that have not had any issues with any of them. What are your thoughts?

I have learned that I need to drain the water heater more often than the rest of the fresh water system or stinky crud will invade. Thanks for the reminder.

I tend to drain and flush 3-4 times a year or whenever the relief valve starts dripping to replenish the air pocket.

Every couple of days is extreme overkill. Once a year, perhaps.

Like you, I only drain the heater when winterizing in the fall. My unit is a 2008 fiver, purchased new in 2008, and I have never had to replace the anode. The heater works just fine. (I have no idea what is lurking inside the heater tank.)
