I see people say this all the time and it is stupid. It may work for you but you cannot say it will work for him. There are hundreds of variables that you cannot predict and that could result in the tank going through his floor. How old is his house? What design is the flooring? What materials were used? Is there any wood rot or damage to the flooring? etc.
Younglin;4664129; said:Do you have a basement? Assuming you do, just put some 4x4 posts under the floor joists where the tank will sit. Just drain you current tank and put the posts in, then fill your new tank. If you don't have a basement you don't have to worry about the weight. But I assume you do have a basement and you said you want to support it from above so adding supports below isn't an option. SO put the tank near a load bearing wall and you should be okay.
