Anyone an engineer? Tank placement question (townhouse)

[GreenSpottedPuffer]

Thanks for the replies, both make sense.

I would have no concerns with the weight on my floor IF I could put the tank against one of the load bearing walls and perpendicular to the floor joists.

I can put it perpendicular to the joists but the best spot I have is above the beam I mentioned in my first post. This beam spans roughly 20' and is made up of 4 - 2x10's (I think, it's drywalled). The tank wouldn't be directly over the beam as there is a partition wall directly over it but it would be in front of this wall. I guess it's worth mentioning that the tank would also be close to where this beam ties into a load bearing wall.

If I could use a floor jack underneath I would but my garage is below.
