I am working with a Febco 825y on a friend's rental. It was discharging out of the plastic discharge vent. I have put in new kit and now it when I turn on the water, sometimes it does a full flush, sometimes it pulsates and then does a full flush, and sometimes it will just dribble out couple little streams about the size of a pencil. I have made sure that the heavy spring is in check 1. I have flushed the entire valve even though there was no sign of dirt in the system.
