LUCCA M58: Safety Valve / Vacuum Breaker Removal

Below is a video and photo instructions for pressure safety valve and vacuum breaker replacement on your Quick Mill LUCCA M58 espresso machine.


Before doing this you will need to remove the panels from your machines. Unplug the machine and allow it to fully cool off.

Tools required:

  • adjustable wrench x2
  • vice grip
  • zip tie

At this point the valve can be removed and a new one installed. If installing a new valve you will need to remove the elbow fitting from the old valve and put it on the new one.
