The plastic impeller hex head is breaking down as I add pressure to break the screw. Do I need a special tool to hold the hex? It is a really bad angle, I don't care about having to replace the part but I don't want to totally distroy the head and make it impossible to remove it.
I see a small oval hole, but I think it's the drain. The small white balls were within the large circular area, floating freely by the blade. Is this where they are supposed to be?
The shaft is spinning freely now.
