What screw driver for this iso-flange?

in THE MAIN WALL
It's too large for a torx 30, and shape doesn't seem like torx. Know what grand flange this is? no writing anywhere. We need the exact driver since it's a bit frozen......



See attached photo.



Thanks,



David

    Hex Key

    When the iso flange won't turn with a large screwdriver, use an allen hex key.  It looks like an older Grundfos flange.

    Flange

    Looks like a Clutch Type Bit ,its a little different but you might get lucky try Grainger item#1YHW5, or you might be able to use a breaker bar w/a flat head screwdriver bit.

    If worst comes to worst, ...

    ... you might replace it with a gizmo like Taco's Shut-Off Freedom Flange. It has a ball valve in it with a regular ball valve handle on it.
