IMPORTANT: make sure the incoming pressure is not above 4 bar; if this happens, install a pressure
reducer.:
The right pressure to brew espresso is between 9 -9.5 bar: this is the bypass setting of motor-pump.
If the incoming water pressure is more than the bypass pressure, the brewed water flux will hit the
coffee grounds too violently, over-extracting it. Over-extraction will negatively influence the physical and
chemical coffee values.
