Crazy idea? Unvented expansion tank

[RockerGuy]

Sounds like a plan! I'll give that a try My "overflow" tank is plastic. I overfilled it slightly last time (about 20% over the "full" line). I think the cap has some type of pressure safety thing that won't let you unscrew it when there is pressure in the tank, it just "skips" when you try and undo it. I'll try harder

try not to scald yourself, since u already overfill it

It's pretty much empty now, I'll watch out for the hot air
