Moving the pieces and reassembling in the apartment basement. Space was tight and had to fit in a space between 2 walls, a dryer and a basement jack. Definitely had some tetris moments.
Finally assembled!
I put nail plates to reinforce the outside supports as an extra precaution. You can also see how the interior polyiso insulation fits on the walls. I put 2" of polyiso on the floor of the tank first.
How the polyiso wall insulation is layered.
