Made the Difference
The old pump in my machine pissed out and I purchased this unit.  Getting to the old pump and installing this one was not very complicated.  All said and done, a 25 minute job.  Since using this new pump, better crema, much quieter,  this pump does not vibrate and choke like the old one did.  Can't say how happy I changed this out, only thing is I wish I had done this when I bought the Breville new.  Nothing against Breville, just his pump is a major step up in performance.
