New house new tank... How much can my floor hold.

I know you're supposed to put tank perpendicular to support beams and next to load bearing wall. Well I have the load bearing wall part but the beams are parallel. How big do you think I could go without support. Or how would I support it and ballpark for guys who have done this.

Ps. I really want a 180.


Tank would go pretty much right above the vents.



16 in spread between beams. Concrete wall on left is outside wall of basement.

Make sure the tank is over two of the beams. Having the sump in the basement will help,with the weight a bit.

Considering you will have point loads on the joist, I would at the very least add some bridging on the first two joices with 2×10s.

Plus 1. And a 4x4 post if you can. You'd need to cut the flooring probably as basement floors are like 2" most of the time. Might be worth the piece of mind.

You'd probably be fine with a 180 , but to be safe, I'd put in a jack post under the outer floor joist. You can get one from Lowes for less than 50 bucks.

+1 and the jack post can be adjusted if you get any sag.

OK - here's what you do: cut out the floor to match your tank's footprint, precisely where the tank is going to go, so you can look through it and see your basement floor. Build a plywood frame, lace it with plenty of rebar, inset a large piece of PVC pipe to run your plumbing and electrical from the basement to the tank, and pour solid concrete into it to form a tank pedestal. Then attach the joists to the new concrete pedestal. Best way to guarantee the tank won't come crashing through.

Heck if you do bridging, you can do it yourself for like 20 bucks (or a couple hundred max from a contractor). Cut 8 lengths that will fit snug perpinidicular to the joist at 18 in spacing, on both the second and third joist. Then attach them with heavy duty nails. A post is nice, but not at all necessary for a 180. 300 gallon, thats a whole different ballpark

Exactly, right underneath where the tank will sit.

You can do more rows and columns as well if you want to play it real safe as that will distribute the weight over a larger area than the tank footprint.
