    I suppose this could have happened before I was putting the laterals in, but I think I overtightened the laterals, and... CRACK! There goes the hub...

    New hub and old hub. Too bad they don't attach the same, but the parts are damn similar for a Pac-Fab Triton from the 80's, versus a current Pentair Triton II.

    Here's what a groove created by sand looks like. This must be the culprit to where sand was blowing back in, though the entire web of lateral spokes were cracked long before I got into the filter yesterday. The spots where it cracked show some aging and wear, as if they'd been there for a while.
