Hello coffee geeks!

First time poster.   Just bought a Nuova Simonelli Mac Cup V off craigslist.  My wife just bought a bakery and was horrified to learn that they only served drip coffee out of airpots, no espresso machine!  We just got into roasting and were pretty big Illy bigots, and our little trusty Krups.   We saw this guy out on Craigslist, going for $500.  The forums showed me what to look for and when we met him at the storage, not at a business, I was a little worried.  Couldn't plug it in.  Same story everyone has, it was just pulled out working perfect.  Skeptical, I asked a ton of questions, and being a total n00b, I couldn't even figure out how to take it apart to look at the innards, and I didn't have any tools.  BUT, dude said, listen, take it home, try it out, no money.  He even refused a deposit.  Trusting guy.  Anyway, got it hooked up the 220v by running a rigged plug from the old hot tub hookup through the window!  Fired it up, all lights lit up.  Good sign.  Boiler starting to warm.  Nice.  The cup warmer freaked me out as they started putting water out, probably normal.  Ok.  No leaks.  VERY cruddy. I took the easy stuff off and scrubbed.  It needs a descale, but I haven't loosed any pipes.  I couldn't get the first group going (I was a dumbass and put the nut on the inner screen (see I don't even know what that this is called, told ya, n00b) upside down.  Got the manual, and it was marginally helpful.  Group 2 ran, and ran, and ran.  Well, it wasn't until the next day that I programmed it to actually do a proper pull time.  SO, still good, now I got group 1 and group 2 all done, programmed and running.  Steam was fine, no missing pieces that I could see.  I think it needs a good descale.  I tested by putting the water in a pitcher to pull from.     Here is the machine.    

I have two questions:  
How much is this thing worth?  I am leaning towards the $500 as it does work.  I have until this weekend to give him a price...
I only get 5 bars of pressure and it looks like it is it sitting on 2 or 3.  Do I need to crank the pressure or is this expected when only hooked up to a vessel?  

I am posting the picts in the next couple of posts....

The pressure valve in question.  Normal for just being in a vessel of water?

and yes, that is gross milk splatter...

I have a similar machine.   Do not trust the gauges, they are trashed usually.  Use a pressure gauge adapted and threaded onto the portafilter.   Also, check the cycle on and off temp using a pressure gauge on the steam wand if you don't want to break loose any lines.  These how tos are readily available on the site.   Mine was in a basement but I planned for full restoration anyways.  My pump was shot, don't run it dry or yours will too.  If you look at their site, you can find wiring diagrams and parts diagrams.   There are still several sites you can get parts.  Good luck.

I'll echo that the gauges are not of the highest quality.... on just about any machine, not just this one. It is easy for them to get out of whack pretty easy. DO get a gauge and check what you have. You should see something in the 140 psi range (10 bar) when pulling a shot, static pressure (not pulling a shot) in the machine while hot is in the 1.1 to 1.4 bar range (this is the machines temp) and if your machines temp gauge is correct, you are a little cool but useable.

The machine brew pressure gauge will show the pressure of the water in the supply line when you are not pulling a shot. When checking the brew pressure, you need a blank basket (you might be able to get by with a piece of rubber cut to fit into the grounds basket if you don't have a blank basket but you will need a blank one for normal maintance and back flushing.

Used equipment is worth what you are willing to pay for it, a working 2 gp commercial machine like yours, sells for around 1K in a used commercial equipment store, give or take a little depending on age and condition.

The group head gaskets will need to be changed as well as a good cleaning is in order too.

You DO need a good commercial espresso grinder, there is NO WAY to run that machine without one, unless you go pods... why bother with espresso at all if you do pods in a commercial environment?

You will likely need at least two grinders, one for "normal" coffee and one for decaf then you might want one for special blends. Start with at LEAST a Mazzer Super Jolly, a lot of shops have them for a SECOND grinder, a Major or better is what you need for your main grinder. You will be putting a LOT of coffee through it (if you do it right and people like your coffee) and you need  grinders that are able to stand up to commercial use. Your Cappresso may be OK for drip in the home (it is not an espresso able grinder by any means) and I would expect a home grinder to die fairly quickly in a commercial environment.


When you say you are (were) "Illy bigots" I am not sure what you are saying. Illy may be OK in Italy as you are close to the source but by the time it gets to the US, it is hopelessly stale. You need coffee that is no more than 2 weeks from the day it was roasted and no more than 15 MINUTES from when it was ground!

Two weeks is the END of the time line for fresh coffee in espresso, so you need to buy it much sooner than that if you are going to have a supply on hand in your shop so that it is used up BY two weeks of age.

To further compliment as well, the RR45 grinders are cheap to be had in comparison.  I have one I paired with mine and with the upgrades available makes it a very capable grinder.  It fits well with it and is "enough" grinder to work successfully.

While the RR45 is positively espresso able grinder ( I have owned one and passed it along here to another member at a good and affordable price) even with the finer ring, it is still a steped grinder. It is a very good comercial starter grinder but I think the OP would be better served with a stepless grinder with this class machine.

Ok, So I got one value for $1000 given the condition, so $500 still seems reasonable.  Anyone else care to comment on how else I can assess a good value?  I think I'm good, but just checking.

Valves.  Bummer that the thing you need to trust isn't trustworthy.  Should I see a rise in pressure when I hook it up to a water line?  Is that really the way it works?  Pressure from line, then the pump ups it a certain amount or do the portafilters play a part in the back pressure to raise the guage?  Should i see a pressure with no portafilter?  I'll do some research on how to do a separate pressure guage, I think I saw a refence somewhere.  

Grinder.  There is no way that I am using the capresso, it's decent for home, not for commercial.  I'll research commercial ones before we start serving.

Illy.  Got spoiled in Italy, the vacuum packs are ok.  The roasted beans should be better, but I don't really see a 'born on' date, just an expiration.  We've been doing a roast then grind as we drink.  Definitely better.

Gauges,
Every machine that I have owned that is plumbed in will show the incoming line water pressure on the machines pressure gauge. I suppose there may be some machines that do not do this as I have not used every machine ever made but, with the 3 plumb in machines I have, they do show the incoming line pressure.

The brew pressure is on top of that but there is a pressure regulator in the machine that sets your brew pressure (the OPV) so there should not be an issue with brew pressure being added to line pressure.

Value, You did not get hurt with the price. Not everyone has the room for a 2 gp commercial machine in their kitchen so the market for them is smaller than for the small commercial machines thus the "value" is good but the selling price is less than a more "home friendly" machine.

Regardless of how the coffee is packed, it goes down hill very fast and even if a commercial coffee (for example Illy) is just opened and the bag the coffee is acceptable, it very quickly degrades... much faster than fresh roasted does.

Roasting then brewing. Coffee needs several days of rest after roasting to degas. Most coffee needs 2  or 3 days to start into it's prime time and most hit their peak at about 5 days to 7 days and then drop in quality. There are no hard fast rules and coffees are different but for a back of the thumb nail picture, the guidelines above are generally accepted.

Add on gauges are not hard, to check brew temp (pressure) you can attach a gauge to the steam wand, this will tell you the pressure in the boiler and thus the temp.

For brew pressure, you can get a rough idea by using a gauge on the bottom of a Porta Filter. It will shot max pressure and for accurate brew pressure, you will need to make or buy something like a SCACE device which simulates brewing by allowing water to flow through the PF at the same rate as brewing.
