Group Head Pressure - from Mains Pressure to Gravity Fed setup.
After getting my Boema single group up and running, all is working fine apart from low pressure at the group head when I pour a shot.
I have noticed the pour pretty much trickles into the cup rather than a creamy, consistent flow resulting in a light brown crema and only about 30mls after approx. 60secs. I have converted the machine from mains pressure to a Bain Marie setup so I am wondering if I have to up the pressure on the pump to allow for the drop in pressure now coming from the gravity fed set up.
From what I have read online, the pumps are calibrated according to their water feed so that leads me to believe that pressure would be way down on mine now.
Would be interested to see if anyone else has come across this.
