    Those damn Mag pumps

    My Mag950 stopped working again last weekend. My first one lasted 8 months. This last one lasted 4 months. Two pumps in one year! Both did not work any better after being submurged in vinegar.

    How long do your Mag pumps last? With everything we have to buy in this hobby, changing pumps three times a year is something I do not want to do.

    What's happening to the pumps?
    They shouldn't be getting enough build up to need a vinegar bath that often..

    well, are they getting all encrusted with calcium around the impellor and impellor wall? If so, it isn't the pumps, it's probably your dosing regimen, ie: too much calcium or buffers.

    Were the pumps external or internal? How is it used in your system (return pump, skimmer, etc)?

    Visibly, I do not see any calcium or carbonate deposits around the impeller. But the pump would work after soaking it in vinegar for half an hour , right?

    The pump is external, taking water from my sump and returning it to the main tank.

    How about intake screens? Maybe some hard shelled critters are getting inside?
    I find it strange because I've been using mag 5, 7, 9 and 12s for years and I may have had to deal with one or two of them in all of that time. I'm not saying they are the best pumps in the word, but they should last longer than that...
    Check inside the impellor housing in the pump itself for deposits. This is the area that heats up and attracts the most deposits.

    No critters found inside. I removed the impeller from the pump and soaked it in white vinegar for 30 minutes.

    I did that with the last pump too.

    No positive result. All I hear is a discreet humming sound in my first pump, and almost nothing at all in the second one.

    Sorry, I don't know, If I were you, I'd bring them back to where you got them and complain- you might get another as a replacement for the one that went after 4 months..

    Are they just stopping one day and you come home and the thing is no longer pumping?
