Izzo Alex Duetto II water hose fitting identification help

OGMacGyver

I have just picked up an Izzo Alex Duetto II and realising that filling the water tank from above is a pain, I will be feeding it with bottled water using a flojet pump. One thing that is not clear is what kind of hose to connect to the bottom of the Duetto? I imagine it will be a braided right-angled hose but not sure about the fitting.

Can anyone enlighten me?

Thanks

Ok I finally got this working.

To run this machine from bottled water I used the following setup:
Right angled braided hose (cone) <-> Metric compression straight coupler (10mm) <-> DM fit female adaptor <-> Flojet Plus bottled water pump <-> 18.9 litre water cooler bottle.

The pump cycles rapidly when pulling a shot but is OK when filling the steam boiler. I will probably add an accumulator at some point to prevent the cycling.

Hope this helps someone

OGMacGyver Unless the bottle is way below the machine… e.g 6ft or more, you shouldn't need a flojet, possibly only a 1 way valve on the hose end.

Ah Dave, I wish you had mentioned that after my first message.

Perhaps I will remove the flojet, however, it does have the benefit of providing some line pressure for pre infusion and a nice pickup for the 5 gallon bottles.

I am new to the e61 so I have a bit to learn coming from a Rancilio Silvia.

OGMacGyver I have just seen this now. I would have shared my experience and possibly saving the flojet (I hope you for this cheap-ish). I used to run my Bezzera from a 10 l jerry can type vessel, just 10 cm above the coffee machine hidden in a cupboard. It was fine even without much hydrostatic pressure.
I did not have pre-infusion so this was not something I had to consider, in your case as you say, you should benefit from the flojet for the pre-infusion.
