Afraid of the answer.....

I think I finally found the culprit!
After a few times of trying to flush and bleed with just distilled water, I saw flow from under the bleeder valve! I guess it wasn't a big enough leak to be visible until I ran it for a few cycles.

Now I do have a few questions on replacing the valve.

Is it a good idea to put silicone or any kind of sealant on the threads of the screws?

Can anyone report success stories on replacing just the valve? The mechanic says he doesn't replace only the valves as he's had too many problems with them.

I see that they need to be handled with kid gloves or it's new tank time.

I'm really hoping that this solves the problem.

Thanks for the help.
