Pompe Valvole Lelit Elektra, La Pavoni, Bugatti, Isomac, Pontevecchio, Quick Mill, Lelit, Zacconi Hello baristas, I managed to reduce noise upgrade my Rancilio Silvia X PRO. I think anyone can do it, no special knowledge is required. 1. Changed the vibration pump to the quietest OLAB 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 New Lelit Victoria already has a Olab pump! : r espresso Lelit Mara X Espresso Machine Lelit Mara X Espresso Machine
