Do most plumb-in machines require external pressure?

Dan, thank for confirming all of the info. Just help me with this and I think I should be ok after: what type of hose do I need from the jug to pump? and the one from pump to machine? vinyl, SS mesh or rubber? I'm a bit confused about the check-valve: does it go on the hose

Rebuild of La Marzocco Linea 4AV.

Yeah , I was expecting water everywhere and sparks to fly...but it went alright. Few leaks. So I finally received a new Procon pump (160$) and a new 1/4HP Dayton motor (50$) I would appreciate instructions on how to plug it all up now. What I would like is to connect the pump to a 5 gallon water

I don't think I gave the steam boiler enough of a chance to fill up or to get hot. Only pressure on the bottom half of gauge was up, to about 3 bars. zero for pressure. Nothing came out of the steam wand. no air, no water, no steam

Rebuild of La Marzocco Linea 4AV.

update: so I learnt a thing or two yesterday...Always plug used equipment before purchase or prior to rebuild. I was obviously excited when I got the machine and didn't bother plugging it before taking it apart. I was optimistic as always. So here is a little recap. I don't have a motor and pump yet...

Rebuild of La Marzocco Linea 4AV.

Bloody hell! That's just wonderful. I mean the new gauge fits and I can tighten it, but I can guarantee that there will be leaks or issues once operational. Thanks for you PM Barry

Rebuild of La Marzocco Linea 4AV.

ok so today i received my parts: pressure gauge upper group o-ring and paper gasket group to boiler gaskets and flowmeter o-rings I'm slightly disappointed. The silicone gaskets don't seem to have the same thickness as the original ones i have in place, and they're not uniform in size. Good thing i ...

Rebuild of La Marzocco Linea 4AV.

oh yeah that makes sense for the whip cream the screen doesn't seem to fit anything on the machine, so it's possible that it came with everything by accident Still waiting for a quote for the missing SS panels. Haven't done much on the machine in a while. Getting a bit impatient
