Hi team. For some time now, I've noticed a strange pump behavior in my Sage Barista Pro. This is my third Sage espresso machine. The first classic Barista worked for a few years, and I upgraded to the Replace Gaggia Classic pump with quieter option? Lets see if this will Improve something. Im sure it will reduce the noise by 40% But they do say a pressure regulator helps with noise and to stabilize water flow aswell Lelit Silent Pump Vibrationspumpe 4000034 Espresso Kultur
