It looks to me like the safety valve overheated and failed.
This introduces a small air leak so the system can slowly vent.

It wouldn't have to come up to 1 atm; it just has to be enough
liters/sec to get the rotary pump misting.

It's pretty unusual for those relief valves to fail. Who made this
one?
