I finally took the plunge and ordered a Vetrano from Chris' Coffee. I will plumb the machine in to make use of the benefits of direct plumbing.
My question is, however, if the Vetrano can be used for a couple of days sucking water from a water container that I'll set up next to the machine. I will need a couple of days to plumb it in and wanted to use it in the meantime. Does one damage the pump by doing so or is this alright?

yes you can and no it won't damage the pump (just don't let it run dry).

Thanks Dave! Good to know!
I see you got an Izzo Alex, a machine very similar to the Vetrano. I was actually deciding between these two machines and finally ordered the Vetrano today. I am sure they're both pretty serious machines. I can't wait for the Vetrano to arrive.

AFAIK, rotary pumps need some line pressure or they might cavitate when trying to suck up water.  Cavitating is not supposed to be good for a rotary pump.  Ask Chris' to be sure.  They should be able to tell you.  A flo-jet on a 5 gallon container should be a way to get around plumbing in.

I too recently acquired a Vetrano, now sitting forlornly in a box awaiting a kitchen redo with plumbing.  I was told by a technician at Chris' that the pump can handle that, but i have not wanted to chance it, and have not sprung for a Flo-jet.

I assure you the rotary pump on the Vetrano can draw from an unpressurised container. It's better if the container is on the countertop, but the pumps can actually draw up nearly 6 feet!  No positive pressure is required to prevent what someone called "pump cavitation"?

Just think about the flow rate those pumps are actually having to handle in an espresso machine....very small.

Also you don't see the Alex pump cavitating...well mine never has and I have run plenty of machines off a container with no trouble, La Spaz Vivaldi S1 MKII, Vetrano, Alex etc..

Also the Izzo Alex Duetto a machine that can be switched to plumbed or internal tanked operation like the Izzo Alex MKII, but with dual boiler, PID and rotary pump will draw from a container, because when I get my test machine next week, that's exactly how I intend to run it...from a large container, I have no intention of plumbing it in....ever

But hey, if you don't want to chance it, even though the evidence is clear that these machines run no problem....fine

Dave is correct! I emailed Chris Nachtrieb, and he confirmed that there is no problem.

By the by, did I mention that Chris' Coffee are super helpful and extremely fast with everything. That's something I haven't found too often among many retailers/distributors. Good to know that the owner is also involved with the community.

Wished I'd known this when I got my Vetrano.
