I too cannot make a correlation to the shock expanding and the pump failing. As for the l/u being deep enough, the water level is well above the pump housing in a tank I have used for 20+ years. Tank depth is 20″. The impeller housing looks fine (smooth and no obvious wear pattern). I removed the rubber water tube grommet and made sure the relief hole was clear. The stainless plate does have a wear pattern at the hub, but is perfectly smooth at the vane end. The L/U was thoroughly cleaned and inspected for water flow. The intake plate (with holes) was replaced by one with scoops). The impeller, though not OEM, was new and is a brand I have used before. Grandma always said: “New don’t mean good”. So, if there is a suspect, that might be it.
