Valve is downstairs tank is upstairs... certainly won't be as easy as typical setups and the large pressure on the valve means the slightest turn will make a big difference. I did it that way as well before, thinking it would be better but you can install the valve under the tank, works pretty much the same. 
 
I was looking at your manifold wrong, thought it ran down the back of the tank and not the perimeter.
