This is a common break on this brand of reactor. I did the same thing. I tried Weld On 40, and it did not bond. It seemed to work on the acrylic, but not the PVC. I threw the reactor in the closet because it scared me how easily it broke, and the fact there is only like 1/2" to bond. That isn't enough imo, and why it breaks so easily there. I was figuring to redesign it by drilling out the PVC fittings and put something else in there, but I haven't got around to that yet.
