Just remember to plug the vent.

I wonder what the leakage rate would be through the main gasket, and 
through the blowout plug? There is always a little bit of steam leaking 
through the blowout plug when my pressure cookers are working, although 
it takes 15-30 minutes for the pressure to drop far enough to let the 
main valve drop, and most of the pressure drop is just from cooling, 
rather than leaking steam.
