Trying to drain water too full
I can't figure out what's what. I overfilled adding more water. Thinking it's too high to be efficient or perhaps safe (?) I want to drain some water. (It's 4/5 the way up with the boiler off). I assume the drain is directly below glass tube but counterclockwise seems to turn a bit with nothing happening. Turned 'closed' (original position) and unsure if assumption is correct or valve is faulty.
