The water for the coffee is take from an heathing exchager and the pump has a big chamber to fill, we will use the vibration pump in any case.

3 bar is 3 bar is 3 bar, whether it's from a municipal water pump a mile away from the direct connect machine, a flo-jet system under the espresso cart, or an Ulka aquarium pump in the case.

But maybe all the people objecting are off the grid, and use wells with hand pumps for their espresso water supply. I just wonder how they manage the hand pump at the well and the lever at the machine when making their shots? I guess you need a real long reach
