Hahahah - I'm seriously laughing but I'm not sure that's how to adequately try and spell it out. Good on you for changing it out, I know sometimes things like that can take a lot longer than they should. I'm laughing because I've just now gotten used to the new quiet return pump on my display tank. I replaced it last week and I'm only now started walking in the room and not thinking "What's wrong? Something doesn't sound right!" For the past few year (it seems) the only time my tank was truly quiet was when something was wrong with the Danner Model 5 and it wasn't working. That particular pump was a true work horse and has been in service on that tank for nearly 20 years. Seriously. I've replaced volutes, screws and a lot of impellers but the main body has been the same for a long, long time.
