Ours did the same split routine and found it is made out of pvc piping material. I used just regular pvc cement and like others with the epoxy, spread the crack and let the cement in and you will not have any more issues. Little or no cost if you have the pvc cement. The vacuum breaker valve body forms cracks after time because of the hand sprayer being worked back and forth when cleaning, which is attached to the breaker.
