Thanks Harold. I thought so but wasn't sure.
I opened that vent a fraction of a turn and the air seems to have flushed out.
Are you saying that it is filling often? Wouldn't that suggest a leak somewhere?
Also, the mist coming out has an antifreeze smell to it. I thought plain water was in there.
Great site and thanks for the quick reply!
: " I also noticed the air vent/scoop has a lot of mineral deposits and is freshly wet. "
: The mineral deposits indicate that the water has been evaporating from the surface for a long time. The pressure reducing valve has probably clogged from all the filling.
