Hi pals,
I'm designing the plans for my mobile coffee cart. I've planned to use a plastic water container (20L - 5 gallons) to act as my "water inlet".
As long as I remember from my barista training, the water inlet pressure advised is around 5 bar (72 PSI).
Since I've planned to use a water container, I will not get that much pressure from the tap of the water container. I'm expecting only the pressure resulting from the earth's attraction.
Therefore, I was thinking if it would be possible to use some kind of pump which would convert the pressure from the container's tap to 5 bar (72 PSI).
I've heard there is a minimum pressure required on the water inlet to operate a coffee espresso machine. I was thinking maybe a too low pressure on the water inlet would damage my coffee machine. Therefore, I'm trying to find out the best solution to use my coffee machine at its best.
I would welcome any comments or suggestion. Thank you for shedding me some light on this question.
Cheers,
Laurent
