Ben I get the moisture in the cup thing for a few minutes every time my b II starts up but it goes away in a few minutes. It's coming from the valve in the top of the steam boiler that has the little o-ring in it. The valve opens when the steam pressure is down and then closes when it builds up. Every few years I have to replace that o-ring with one of the red ones and it works fine for another year or so. I have several if you need some. My steam issue is not from the opv. I'm guessing it's a vacuum breaker. I was having trouble with my pump not coming on last year and replaced the controller and it fixed it. Not sure if that's your issue but it may very well be. As to the pstat. I got another jager last year from Chris and it's been working fine. they had a new batch and both of ours that failed had old dates on them. Hope I helped.
