I don't know how to do the mathmatical equations to figure this out, but I will share that we rented an Aqua Doula, and cracked a main support beam! I have 90 year old home, and we set it up in the dining room on the first floor. I was literally in labor, in the water and we heard a VERY LOUD CRAAACCCKKKK! Dh went to check it out, and fortunately had the good sense not to mention anything until after the baby was born though!
If I were you, I'd set it up directly over the most supported areas on the floor, and I'd stick to the lower levels of your home.
