A subject of debate. I set my backflush pressure at 9, and my shots pull at about 8.5. I believe factory is set to about 10 for backflush, and about 9 for shots. To adjust this, you need to set the pressure "up" to your intended target, i.e. you can't just dial from 12 down to 9. In your case, if you go to 12, and while holding that pressure dial the OPV down, you will need to then release pressure and build it again to see where you are. If you're at 10 now, dial it down again and release pressure, build pressure, check. If your OPV were set too low, you could just dial it up to the desired setting. So if you went from 10 to 8, for example, you could build to 8, then dial up to 9 and be golden.
Bottom line, release and rebuild pressure between each reduction of pressure setting, but just build pressure and dial up if you need to increase pressure setting. 12 is way too high; 14 is off the charts too high. The balance between volume, grind, tamp, etc. is very hard to hit at such high pressures, because you're having to really over-compensate to try to avoid channeling, etc. bmc "Faith will move mountains, but you'd better bring a shovel....." > From: MBB <[EMAIL PROTECTED]> > Reply-To: <[email protected]> > Date: Sat, 20 Sep 2008 12:35:57 -0700 (PDT) > To: Brewtus <[email protected]> > Subject: Change in Pressure > > > I just recently noticed on a backflush my pressure has risen from 12 > to 14.
