well this is embarrassing.
Downstairs looking how to run things and thought "never have looked at the a/c unit's A-coil". Pull off the cover for the humidifier on the side of the furnace and see the tray is full of water and water is dripping from the float!!!
I know I turned the water off like 6 years back. Try to turn the piercing valve but it's already screwed down tight and can't go tighter. Looks like it's been running a while from the deposits, maybe not 6 years but some.
Had a spare JG valve so installed that after the other valve.
