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?

I've discovered why it failed.
This was a valve that I pulled from our "random extra parts" closet
HPS model 145-0040K-24V

I should have pulled the spec sheet on it long ago... it required
24VAC and we were feeding it 24V DC
I'm surprised it worked fine for the first week.....

Geez, major meltdown. I'm also surprised it didn't smoke in the
first few minutes.
