To me it looks like the back end of the jet pump and not the wear ring. Doesn't it look like the black is going towards the center?
Can the wear ring peel?
I thought it was one solid piece.
later that day.....at 6:32pm
I stand corrected
OK, I saw a close up of the pump. I see that the ring butts up against it. What would cause it to "peel back" as if you shaved it.
Impeller blade, Glass, rock???
