Hopefully it's just low on refrigerant. Unless anyone has anymore ideas.

Odd indeed.

The ball valve is pretty good evidence that the water flow is stopped.

The cold return line is a pretty reliable tell that the freon level is high enough you should be seeing some cool air at the vents.

You may be very close to enough freon but not quite there.

Remember, R134a acts like a step function as you bleed in the freon... nothing, nothing, nothing, then bam, cool air......
