Thanks guys. I know I've seen it drop in pressure with a blind PF. Of course just now I went and did two blind PF runs and it held both times. I then pulled a shot and it seemed to hold. I then did another blind PF. It held. But, an oddity was that maybe 20 seconds later, with nothing on, the pressure gauge just went up to 9 bar. The machine was not working (everything was silent), etc. I flipped on the brew lever for a second or two and the pressure dropped down, and then stayed down once I turned off the brew lever.
My guess is the OPV is relatively inexpensive, but a new pump is probably fairly costly? I'll call WLL today and at least order an OPV and see what they say on pumps...
