Kelvin, the reason that your brew pressure will rise to your opv pressure during warmup and rise slightly when the brew temperature drops is because heat is rising in a closed space causing pressure. Next time you're heating up the Brewt, take the opv tube out of the reservoir and it will be dripping because the pressure rose to the opv limit (if the opv wasn't there, you would blow a gasket or tube). Nothing is wrong. Ben is right, normal idle is only a couple of bars.
