My waterbox 230.6 upgrade is arriving this week and I'm tackling floor reinforcement before it goes into its place. I have the old 80gal moved out of the room in preparation for this.
I went under the house today to have a look at the space. Joists are 2x6's spread 16" on center. Tank will be running perpendicular to them, up against the load bearing wall along the foundation. I was pleasantly surprised to see there was a 6x6 beam with cement footings running the length of the room ~5' from the foundation wall, a relatively short span. At the very least I'm thinking I should sister up the 2x6 spans between the foundation wall and that 6x6 beam.
Or just run another 6x6 on house jacks perpendicular to the joists ~2' out from the wall.
