Thanks to all who responded to my query! All is good, the pop up valve has popped up! I applied a liberal spraying of silicon yesterday and this afternoon, after a couple of tugs, it popped up. I’ve sprayed it again with silicon but when exercising the thing, it feels gritty. Interestingly, I’ve always been able to turn it in a circular fashion but that did not translate into vertical movement.

I think this little valve is like an appendix, not serving an obvious function since pumping anti freeze through the system displaces any water. Were I to just leave it closed and quit obsessing about it, life would go on. BUT, it’s there, it once worked, and I’m apparently more than a bit anal. If it’s there, it should be working. Happy ending! Thank you all!
