Rocket Espresso R58 Cinquantotto Dual Boiler Espresso Machine Reviews


Ask a Question
  • Good afternoon, gentlemen. What should be the minimum water pressure in the water supply when connecting the machine with a hose? If I lower the hose into a 19 liter water bottle, is that enough? Do I have to connect an additional pump, such as Flojob seria 5000? Regards. Yuri Romanenko.

    When you connect a plumbable machine to directly to the water main, there is a lot of pressure in that pipe that has to be reduced to work with an espresso machine.  We do recommend using a Flowjet Bottled Water System Series 5000 for the connection to an external bottle of water.  The Flojet unit shuts off automatically when the bottle is empty.  It has a built-in check valve to prevent back flow.  It will operate with a maximum flow of 0.6 GPM (3.8 LPM) and a maximum pressure of 40 PSI (2.8 bar).  The kit wshould contain everything you need to operate your machine with a larger bottle containing softened water.
