The upper dump valve on your ScubaPro BC gets a new seal everytime an Air2 gets serviced. Why not take it to the dive shop for less then $20 ? The seal is only maybe a $1. part. Dive with your Zeable ranger enough tn the chlorine pool and the rubber seal will start to deteriorate also over heavy use.
