Apartment + Big Tank = ?

[fortheloveofcrabs]

I live at 'The View' in Edmonton (it's 5 floors, and made out of wood) and when my wife and I bought the place, we did a little research into this. It turns out that someone in their last building had a 250 fresh water tank in their place and it was fine. Another person had a full sized grand piano (those are heavy, and only have 4 legs). The ammount of weight doesn't seem to be an issue, but rather where you put it. If it is by a load beagin wall, you could any sized tank and it would be fine. The larger the tank, the larger the foot print, and thus, the lower the PSI!
