Hey all, I am moving to El Sobrante/San Pablo and I want to have the floor checked out where I plan on moving my tank to. Any referrals of local structural engineers would be helpful. Thanks in advance!

You don’t need that. If you’re worried. Just toss in a 4x6 with some floor jacks. Those things can handle a lot of weight. If you need help just dm me.

Attaching it correctly is not trivial, but you are right that if the crawlspace is accessible, additional lumber and support can be added to help.

What size is your tank?

I have the same sized tank, if you look up my Wifebane tank journal, I have a few pics of what I did under the house. Basically I cut two squares out of the concrete "rat proofing" in the crawlspace, then dug it out about a foot, pouring in some concrete with some rebar and then plonked a concrete deck footing in there, then I cut and measured two 4x4 posts and put a 4x6 beam under where the tank would go, and put the posts under to support the beam, connected by steel Simpson galvanized steel connectors.
In retrospect, I probably could have saved myself some headache by using floor jacks instead of the wooden posts because, they are much easier to adjust and didn't require exacting measurements to install. I don't quite remember but I think I had to cut another 4x4 post and then I used a bottle jack to slightly push the beam (and floor!) up a touch to slide my exactly-cut 4x4 posts under the beam. A floor jack could have also helped with that part! Z


I thought I had photos of the completed beam/posts, but I guess they weren't on photobucket or something, I dunno.

Oh yeah, I forgot, the 4x6 beam I installed had to be shimmed on top due to the unevenness of the actual floor joists! So I bough a piece of flat steel, cut them to about the width of the beam (in theory 4") and then painted them black with rustoleum paint, I used one or two of them between the joist and ht beam. Some of the joists just did not make contact with the beam.
