First off, thats not an enderle setup, that is a Kinsler system. They have a funky way of running the plumbing .The pill holder ( what kinsler calls it) seems to be in the right spot. Make sure the pill is in correctly. I think the chamfered portion of the jet faces the barrel valve with the spring on the back side of it. If it were me I would call kinsler about this and ask them. Like I said they have a funny way of plumbing there systems which can cause you to go crazy.
