Our service center has seen numerous unusual cases over the years, but when they received Jeff Kisamore’s repair order earlier this week, the entire office couldn’t help but take notice.
Jeff had sent us an original D100 Dosatron injector – one of the very first Dosatron injectors ever sold
in the US. This unit was so old, it pre-dated printed labels for our injectors. Furthermore, the original factory seal was still in place, meaning that this injector had never been opened for routine maintenance!
We couldn’t believe it. We knew our injectors have a really long product life, but this unit had to be at least 20 years old, and had never been serviced. We had to call Jeff to get his story. Here’s what he told us:
I bought my Dosatron brand-new about 20 years ago. We first used it to medicate sows, but for the past 10 years or so, we’ve been using it to give our show animals vitamins and electrolytes. Everyone on the show circuit dislikes us, because our show animals consistently win, and I’m sure that the vitamins and minerals they get through our Dosatron are the reason. Over the past couple of years, I’ve even been loaning our Dosatron to my brother for his animals. Until recently, the injector has worked perfectly.
Our technicians were able to determine that the necessary repair was the replacement of one inexpensive top seal, valued at approximately $3.22. This means that, even without routine maintenance, the injector still only needed a minor routine wear-part replacement. Instead, we’re giving Jeff a brand-new D128R, which we hope will give him many more years of reliable service.
