Double check that sub floor thickness, sagging between joists is not common with 3/4 plywood.
Like I said, looks like 1/2 inch to me
While not common 24" centers is a decent span, even for 3/4" plywood.
when you say decent span even for 3/4...I assume you mean its on the verge of to much span.....bob
It's possible depending on how many plies.
Even without the T&G, plywood rated for structural sub flooring is different than standard plywood.
It has layers that are not just altered 90*, but one or two that are at a 45*, we used to call it StrudyFloor
Regardless, his subfloor is neither T&G or subfloor rated.
I still have a hard time believing it is 3/4
