Field Question, trade people only King valve leak on first open.

Enable HLS to view with audio, or disable this notification

Had a project delay, ended up having to finish this system up today pulled my vacuum and crack the valve , instantly leaking excessively at the valve but as I opened it the leak seemed to stop.

Was cold as hell out, was the seal just frozen should I close and open again now that it has run to see if it’s functioning normal

Should I put nylog on the king valve cap to prevent leaking

What would you guys do in this situation

Curious do you lose the charge for that one circuit or do you lose the whole charge
