This is a very quick walkthrough on how to reduce the brew pressure on a Rocket Appartamento. I found there was quite a bit of misinformation online on how to do this, and what little accurate information I could find was pretty vague. By adjusting the OPV, I was able to reduce my machine's pressure from 13 bars to 10 bars against a blind basket, yielding around 9.8 bars during brewing. I found this produced noticeably better shots with less channeling. 

As always, make sure your machine is off, unplugged, and cold when poking around the interior of the machine, and any adjustments are done at your own risk. Safety first!
