[Patch]

Got a 180L today. Arrived at 150 psi. I drained 25L out of it to fill up one of my dewars so I woudn't get stuck without LN2 unexpectedly. About 7-8 hours later the thing was popping off at 350psi every 5-10 minutes.

The liquid removal port valve was stuck so I couldn't drain it (not frozen at all). I opened the vent valve and the sucker took 1/2 hour to get the pressure down to 0!

After some effort and some assistance from channel locks, I got the liquid valve to open.

Closed the vent and waiting for pressure to build up again.

Makes me nervous to have a damn bomb sitting in my garage popping off at 350psi every few minutes.......it's loud too.

Is this normal? My last 180L rental never popped off. (Of course, it was gone in a few days........was more like an 80 L rental...)
