I just noticed one of my 6045's was not moving any water. Upon further investigation I see that the chrome rod that sits inside the magnet broke and took the prop with it. I have had these now for about 8 months and I am a bit surprised on the reliability of these small pumps. The mount for this one also is now very loose which I noticed when removing it to find out the problem. Just wondering if anyone else has had this problem. Thanks Rod
