I saw this post in the parents chat room on CWD and wondered if anyone else has had a similar experience recently. I'll direct Tom here if there have been others. Thanks. Tom Son Grant dx'd @ 11 months; Now 14 Years Old. Sun Mar 27 11:24:37 AM EDT 2011 Grant's been pumping for 13 years. All of a sudden we have experienced a huge increase in the number and frequency of no delivery alarms. Initially we thought it was due to change from Minimed 722 to 723 pump. Now believe it is caused by change in Minimed reservoirs. "Old" reservoirs had a clear cap. "New" reservoirs have a white cap. So, my question is: have others experienced an increase in no delivery alarms associated with the new white capped reservoirs? Thanks.
