Hey, I tried that mod out and I think it damn well
worked! I took everything out and epoxied the impeller etc... and what's funny about the mod is that the pump does a little rumbbling to get the water moving at first, then swooosh everythings flowing and MUCH quieter, though I don't have a db meter, I know the vibration has been softened and the humm is at a normal and acceptable level (meaning I can't really notice it cause of fans etc.) Thanks for that link, you saved me months of ongoing frustration!
