The comparison to a home HWH is not really relevant.. Unless you let your home HWH sit for months without using it at all?? I know my folks drain their HWH before they Snowbird for 6 months..
Bet you use yours everyday.. :)
To let 6-10 gallons sit for months... I'd just drain it.. Couple of weeks, sure leave it alone..
I have a anode rod in my new trailers HWH... I don't want it just dissolving away for no reason because I don't want to drain 6 gallons of water..
I drain mine by opening the low point drains and then open the pressure relief valve and it all drains without any tools.
Whatever works for you is the way to go in the end..
Good luck! Mitch
