I have just found a supplier of a gauge here,just ordered one,I would prefer to make this as simply as possible,if I went for the non value option I would still be able to get a true reading? back to top D4F Senior Member Joined: 15 Mar 2012 Posts: 1,222 Location: USA Expertise: I like coffee Espresso: Gaggia Classic PID Grinder: Preciso Posted Sun Mar 18, 2012, 12:57pm Subject: Re: checking pressure on the Gaggia classic   90 degree elbow, portafilter to guage will work.  You can still similate flow with a calibrated bleed through the steam wand while running the pump.  Your 60-70 ml in 25 seconds through the steam wand while measuring pressure.  Otherwise just measure static and make around 10.  Some disagreement about actual static value. back to top sniggings Senior Member Joined: 27 Apr 2007 Posts: 49 Location: UK Expertise: Just starting Posted Sun Mar 18, 2012, 1:00pm Subject: Re: checking pressure on the Gaggia classic   cheers,around 10 bar sounds it could well be a big improvement,I would be happy with that! back to top D4F Senior Member Joined: 15 Mar 2012 Posts: 1,222 Location: USA Expertise: I like coffee Espresso: Gaggia Classic PID Grinder: Preciso Posted Sun Mar 18, 2012, 1:01pm Subject: Re: checking pressure on the Gaggia classic   You may already know about filled vs non filled gauge.  The nonfilled is a little bouncy but easily readable for this and is cheap.  You set it once and may occasionally check it if you suspect a problem, but in practice, set and forget unless you have a brew/flow problem. back to top sniggings Senior Member Joined: 27 Apr 2007 Posts: 49 Location: UK Expertise: Just starting Posted Sun Mar 18, 2012, 1:07pm Subject: Re: checking pressure on the Gaggia classic   yeah £7! a bargain lol how is the connection made to the PF? just remore the spout and the tube just pushes on to the PF? back to top D4F Senior Member Joined: 15 Mar 2012 Posts: 1,222 Location: USA Expertise: I like coffee Espresso: Gaggia Classic PID Grinder: Preciso Posted Sun Mar 18, 2012, 1:09pm Subject: Re: checking pressure on the Gaggia classic   Pushes?  Screws on snuggly to measure those pressures. back to top sniggings Senior Member Joined: 27 Apr 2007 Posts: 49 Location: UK Expertise: Just starting Posted Sun Mar 18, 2012, 1:24pm Subject: Re: checking pressure on the Gaggia classic   oh right, so the spout is already screwed on there,not had it off yet,didn't realise it was already threaded,bit of luck there then. back to top D4F Senior Member Joined: 15 Mar 2012 Posts: 1,222 Location: USA Expertise: I like coffee Espresso: Gaggia Classic PID Grinder: Preciso Posted Sun Mar 18, 2012, 1:27pm Subject: Re: checking pressure on the Gaggia classic   You will soon find that it is difficult to remove, though not bad with a vise and padding.  Mostly due to thread lock.  I used teflon tape on the new fitting and they are easy.  I left off the double spout when done. back to top sniggings Senior Member Joined: 27 Apr 2007 Posts: 49 Location: UK Expertise: Just starting Posted Sun Mar 18, 2012, 1:30pm Subject: Re: checking pressure on the Gaggia classic   will be moving to a bottomless PF soon,shame the gauge wouldn't work with one of those. back to top showing page 2 of 3 first page | last page previous page | next page view previous topic | view next topic | view all topics Discussions > Espresso > Machines > checking...   updated topics   new posts   new unanswered     search   faq   sign up   Not Logged in: log in Discussions Quick Jump: Select Espresso Discussions --Espresso Machines --Lever Espresso Machines --Grinders - Espresso --Espresso Mods and Restorations --Espresso Blends --Questions and Answers --Latte Art and Etching --Barista Jams Around the World --General Discussion Coffee Discussions --Machines and Brewing Methods --Home Roasting Talk --Questions and Answers --General Discussion Columns, How-Tos, and Reviews --Holiday Gift List Feedback --CoffeeGeek Columnist Feedback --Detailed Review Feedback --Products First Look Feedback --Quickshot Review Feedback --Guide Article Feedback --How-To Article Feedback --CoffeeGeek Podcast Feedback Members Forum --Bug Reports and Suggestions --Buy, Sell and Trade --Retail Coffee Jobs Offered / Wanted Ads --Coffee Recipes --Cafe and Bean Reviews --CoffeeGeek Site Info and News --General Off Topics World Regional --United States West --United States Central --United States East --Western Canada --Eastern Canada --United Kingdom --Western Europe --Eastern Europe, Nordic Countries, and Russia --Central and South America --Australia, New Zealand and Asia Symbols: = New Posts since your last visit      = No New Posts since last visit     = Newest post Forum Rules: No profanity, illegal acts or personal attacks will be tolerated in these discussion boards.
