I noticed that one of my 6025s was not working so I took them down to clean them and I saw that there was somthing strange about each of these. The one in the top of the pic, the metal rod was not attached and it came out with the magnetic white propeller thing. The one at the top of the pic is the one that was not working. The other pump was working fine but the pump looks distended. Kind of busting out in the middle of the blue writing. I was not sure if that was normal. The clamp for this pump actually broke but I highly doubt that has anything to do with the pump. Anyhow I was just wondering if there was something I could do for the one pump, are they 2 different versions? Thanks.
