I live in an old house (about 100 yrs. old). On the 3rd floor I have approximately 1500 lbs. of water weight between two rooms. 8O (one 55 gal
, two 29 gals, and one 20 gal
) I also have solid oak antique furniture. Heavy....very heavy 8) . I am waiting for my house to split right down the middle. My fiance says he has a secret scuba stash in case anything goes wrong. Have an engineer look at your house (or someone that knows about building structures i.e. carpenter, architect). My fiance used to build houses and explained the beam structure and how much weight it can hold etc.... It put my mind a little more at ease.
