this water heater is in a mobile home so the cold water inlet is towards the bottom, I was going to drain it but the hose bib at the bottom is so close to the floor I would have to build an adapter in order to hook a hose up to it, which I may do just didn't have time last night. This WH is a dual element, I saw on lowes.com they have 3 specifically for mobile homes, but they are single element, I wonder if the new single element one's work better now than my older 2 element WH?
