Okay! It supposed to go like this, per oldman Dietrich's son Martin:Salt and acid have an affinity and have a complex relationship.
I have never had an espresso machine so can't comment on them. I have had several K cup pod machines and in every case the distilled and RO (reverse osmosis) water I tried resulted in a bitter tasting cup of coffee. I just tried some different RO water this week with the same results again.There is rather a lot wrong with that page, but with espresso as well as problems from hard water, extremely soft water is corrosive in machines, and you need some alkalinity. RPavlis water is a simple espresso water recipe. There are many more, you can start down the rabbit hole at the following link.

RO doesn't really have enough mineral content to properly extract coffee, so you'll want to doctor it.

The local water here just plain sucks and I do not drink it at all for coffee or even iced tea which just leaves me with bottled alternatives.
As I understand it, and if anyone knows better, fee free to correct me, water with a very low mineral content, like distilled or RO water increases extraction, so it may over extract coffee and cause bitterness.I have never had an espresso machine so can't comment on them.

I actually tried half RO and half spring water that I normally use and still found it lackluster.RO doesn't really have enough mineral content to properly extract coffee, so you'll want to doctor it. "Holy Water" is a good place to start for filter. https://espressoaf.com/guides/water.html
Other way around, really - some amount of dissolved solids helps extract.As I understand it, and if anyone knows better, fee free to correct me, water with a very low mineral content, like distilled or RO water increases extraction, so it may over extract coffee and cause bitterness.

There are cost effective ways of fixing tap water, if you know your precise situation, and are prepared to put the time in to understand how. There isn't a one size fits all solution as tap water is very variable, so you need to tailor your solution to your situation.The local water here just plain sucks and I do not drink it at all for coffee or even iced tea which just leaves me with bottled alternatives.
that R really grinds my gears now that I'm looking at it in this pic...
This is exactly the kind of thing I think is fishy in my machine.Doing some pretty in-depth maintenance tonight - I took my machine's 3-way solenoid group valve apart - I think the flow restrictor in it was scaled up pretty good, so the water debit (no-restriction water outflow from the group) was abnormally low. Which it certainly was, at about 5.3ml/s (usually 6.5-8.5ml/s is typical for pump machines).
Update: And wouldn't you know it - cleaning the bloody thing bumped it to 6.5!
That sounds more like there might be a bit of air leaking in from somewhere and doing that backflush is purging the air? I'm in a discord with people who know a lot more about this than me, I can PM you the link if you like.This is exactly the kind of thing I think is fishy in my machine.
Haven’t had a chance to play with the pump or pressure adjustment yet.
One of the things I had started doing that seems to help a little is running a backflush before I start pulling shots. My first shot is still a little squirrely but it is closer to the following shots in yield… maybe a 2g difference instead of 3-4g.
Considering I didn’t do a descale for 4 years…
This is why I asked about the solenoid a little bit ago.
At this point it’s looking like early next week is my window for replacing the pump.
Good news is that will give me an indication of any mineral buildup. *fingers crossed
Ya… I researched it a bit a week or so back.That sounds more like there might be a bit of air leaking in from somewhere and doing that backflush is purging the air? I'm in a discord with people who know a lot more about this than me, I can PM you the link if you like.
Anyway, yeah - the solenoid on Silvias is behind the front panel. Two 3mm hex bolts hold it on. The coil is attached with a nut and washer.
Run for 30 seconds onto a scale that measures in 0.1g increments, divide by 30. My machine is now sitting at 200ml in 30 seconds up from 160.Ya… I researched it a bit a week or so back.
Would be interested in hearing your method for testing flow output…
Just running for 10 sec and weighing/measuring the output?
I think it's hard to beat a Comandante C40 grinder, and a Hario Switch (with Sibarist papers if you're feeling fancy). Comandante is sturdy and reliable, plus so many places will give you recipes for it. The Switch is super versatile - you can use it for pour over, immersion, or a mix of both.How do you drink coffee when you are on the go (on vacation etc.), show us your portable kit
