Hey all,
Would it be okay to run my espresso machine off of a bottle using a shurflo / aquatec style pump without an accumulator for a few weeks? I'm not sure of my final setup yet and if i'm going to go with a 2 gallon accumulator or one of the mini ones. I can't see any reason it wouldn't be but I figured I'd ask the brain-trust here just in case.
Thanks!

It's not a problem, the pump will just cycle each time you draw water instead of time-to-time with an accumulator. At espresso flow rates, there's no need for a large accumulator. On the other hand, if you're going to use the pump to run a pitcher rinser, for example, then a larger accumulator would be worth having.

Though I've read numerous times it is not a good idea, I run my Elektra A3 with the pump drawing directly from a 5 gallon bottle. No external pump/accumulator. I primed it by having the bottle higher than the machine, and then put a backflow preventative valve on it.
Supposed to have 4 bar pressure, but when we moved I had little to no choice where the machine is and no in-line water source available. Been running this way since 2013 so seems to be OK...
Just have to very careful about water level in the bottle.

Thanks, that's pretty much what I was thinking. If this machine ends up living in my house, I'll skip the rinser, but if I end up taking it as a mobile catering unit I'll want the rinser and I'll need some sinks as well. Of course, if I take it mobile, space will also be at a bigger premium, which is frustrating.HB wrote:It's not a problem, the pump will just cycle each time you draw water instead of time-to-time with an accumulator.
