Cracking up

I’ve been pumping for a little over 5 years with MiniMed. I had my first pump for its entire 4 year warranty. I never had any problems with it, not even a loose battery cap.

I got my second pump at the end of February 2008.

Recently, I noticed a crack near the reservior chamber. From my perspective, it seems like a pretty large crack, but it is not actually affecting the functionality of my pump right now.

Since I have never had a problem before, I don’t know what to think. I know I can obviously call MiniMed and ask them, but I thought I would put it out there in the diabetes blogosphere first to get some expert opinions.

  • Well, it looks like it’s just the plastic casing, and MM never claims the pump to be watertight (ie, you have to keep it out of water anyway), so I think if you can live with it cosmetically (or until it does interfere with function), I wouldn’t waste time talking to MM when you could bolus for some M&M’s, and continue enjoying life.

  • IF you can get it replaced, do it. They replaced my pump two months before my warranty expired. They fedex’d me my new pump and sent a shipping label and packaging for the old one. -TOTALLY EASY PEASY

  • A (4) year warranty is a (4) year warranty.

    As an ex-plastics engineer, I’d question material flow around that cored window as a possible cause of a “nit line”. If you didn’t crack the case with serious force, maybe a weak “nit line” is responsible, or aided the issue.

    Call and see if they’ll replace it.

  • I had the exact same crack on my clear MM522. It wasn’t causing any problems but I called MM just to ask and they replaced it. I was glad they swapped it because I wanted to switch to purple anyways 😉

  • I replaced mine about a month ago for the same crack… clear as well… got a purple one too… wonder if it is a common problem… mine was 3.5 yrs old.

  • I’ve used three different 522 pumps and every single one developed this crack within a few weeks (although it wasn’t the reason for replacing any of them.) I think it is to do with the squared-off design of the window. The corner creates a weak spot that supports the development of a crack. I now use a 722 and the reservoir window on that is rounded. It isn’t cracked after more than 6 months.
