Hello I am pretty new to working on water heaters. My water heater is a Whirlpool and is pretty old. (2010) But I was trying to drain it so that I could clean out all the old sediment and rust that I am sure is in it. But I ran into a problem with the cold water inlet valve. It looks like the last plumber who worked on it must've put the valve on wrong because the furnace tube is right in the way as I need to turn it off in order to drain my tank from what I've read. So my question is what will be the easiest way to switch that valve out or fix it? I tried for a minute to loosen that nut so I could possibly move the valve to the bottom so I could maybe turn it off that way but then water started leaking. Thank you and sorry if this is a dumb question.
