GB/5 steam boiler vacuum breaker hiss
hey all, i installed my new (to me) 3 group semi-auto gb/5 tonight, and while the shots were pulling fine, the vacuum breaker on the steam boiler continued to hiss at a medium volume until i shut the machine off and bled the pressure off. does the gasket or teflon thingy in the breaker need to be replaced? is the gasket easy to find at a hardware shop? counter culture used to service it, i'm going to call them tomorrow but any help would be much appreciated.
other than that, this machine slays tho. i easily pulled the best shots i've had in ages without the grinder even being dialed in.

ok i got a new vacuum breaker and some o-rings from espressoparts - they're installed and no steam leak anywhere EXCEPT from somewhere in the pressure relief valve. considering it is, you know, a pressure relief valve, should there be a very slight hiss and steam leakage from there? i put a spoon down the little cylinder and it fogged it up just slightly. normal?

Ideally there are no steam leaks. My goal is always a dead quiet boiler. But a tiny hiss isn't really hurting too much. So I guess my answer is that a tiny bit of steam leakage is common, but not ideal.

Fixie, derailleur or single-speed - you've gotta get to the coffee shop somehow.
Sounds like a great new shop Jay. Congrats and good luck!
Multiple roasters offers the advantage of hand-selecting what you believe are the best coffees available. At any given time, no roaster can ever claim to have all of the "best" coffees in the world. Why not pick and choose from great roasters?

I love 1,000 Faces, my dear friend Erin is working for them, that's how I got the connection to serve their coffee up here in NY, I am so impressed with everything they send me, what a great roaster!!!
My 18 month old, Eden, refuses to drink milk without a coffee bean to chew on while she's at it.
Thinking that way we have a reliably wonderful (and user friendly) house roast in Madcap. A lot of coffee consumers like their "familiar" cup of java and aren't looking for a "challenge" with their caffeine hit. For all of us who are coffee geeks th…
