I need some help/advice. I am using a quiet one 4000 as my return pump and for the most part is has been good, until today that is. The power went out this morning while I was at work and I just got home to find that the pump had not re started. I could hear a bit of a hum from it but the impellor was not turning. This happened once a couple weeks ago as well when I had to shut it down to do some re-arranging. In both instances I had to unplug the pump pull it out of the sump and move the implellor by hand then when I replaced it in the sumpit started to work. I have taken it apart and can find no visible problems so what now? This obviously cannot be left to go on this way, my tank had dropped 5 degrees in the time I was away, if I had been further along in stocking it could have been a very costly problem.
Anyone have any ideas on how to fix this?
Or can you suggest a good replacement pump in about the same price range..
