At the suggestion of an engineer, I have decided to reinforce my I joists and build a pair of supporting walls underneath where my tank is. I measured from the bottom of the joist to the floor and for 104 5/8". I built my wall lying down so that I could get long, perpendicular nails in with the idea that I would raise it into position. It measures 104 5/8 as well, miraculously. However, I start to get a lot of resistance at this point when raising it and it has a way to go still. It's it somehow too tall or should I try really hard to bang it in there? If it is too tall, should I try to just sand down an 1/8th or something? Could even do it just where the joists cross.
Thanks for the help
