Re: Are Sierra thermostats OK?

[frankr]

But I still go back to my original question. If the ‘stat does not have a notched poppet, how can the water flow up from the cavity that it sits in, and if it can’t flow, how does it present itself to the pellet? Unless the gap in the cap is supposed to leak enough to let some through. Seems iffy to me. I still think it needs a notched poppet.
