From what source to people get the purified water (i.e. with near-zero TDS)?

MWJB I lifted the text from the link that Jake sent, making you right!

Is yours just plumbed in under the sink? I assume you can fit a spur off a cold water pipe and add a valve

PianoMan Perhaps it’s because I have to flush the group head when I make a coffee

Yep! There’s no way I would have an old school HX machine if I was using distilled/RO/Bottled water as there’s a lot water wasted. I had a Rocket Cellini back in the day for 3 months or so, and experience this first hand. Flushing the machine before every use consumed like 200ml of water per session, wasted just for that. Two coffees a day, times 7, and that’s 2.8L wasted.

dfk41 The price varies almost daily. I paid £279. It is quite quick, has worked faultlessly in the 2 months I have had it. They are a global company. I used to use the Osmio Zero system which is nearly £200 more. I do have to add bicarb back in to the water for use if my coffee machine but for me the pro’s outweigh the con’s

I have just checked Amazon and it is currently £269

I actually ordered one from Amazon to give it a try.

MediumRoastSteam it's looking increasingly like I already have the best (least bad) solution. 😳 Even with a PID I still have to purge the head… and I have about five double shots a day. ⚰️

dfk41

Admin I will be interested to see how you find it. I am completely non inquisitive or engineering minded……that is your job!

MediumRoastSteam

dual boiler next? 🤪👍

PianoMan

MediumRoastSteam I'm not made of water! Okay, technically, I am. 😅

Have it at work.

Take 2 5l tubs and fill both waste is plumbed into the drain

PianoMan

Cuprajake

I do that!!! (I work from home)

MattH sorry to be clear i use the countertop osmio zero 👍

I use a Skuma counter-top RO machine with their Coffee Balance for remineralisation.

PianoMan

mathof2 How long do the filters and infusion last?

mathof2

PianoMan The infusion bottles seem to last about four weeks with my normal usage, 500ml of infused water per day. I've had my machine about a year and haven't changed the filter yet.

PianoMan

mathof2 Can you run the machine without an infusion bottle?

mathof2

PianoMan I haven't tried, but you can certainly run it with an empty bottle. You can also switch the infusion off at the press of a button if you want to draw pure RO water only.

PianoMan

I'm full of questions, but did you ever test your water, to see what the current TDS levels are? They're under ten on a "Zero Water" filter, but I would tolerate a little higher than that.

MediumRoastSteam

PianoMan They’re under ten on a “Zero Water” filter

A ZeroWater filter, without the quotes around it😉, should give you a TDS of 0ppm. You would usually change it when it displays 4ppm.

When sodium bicarbonate is added at a rate of 100mg/L, the TDS then reads around 50ppm, from memory.

PianoMan

MediumRoastSteam I wanted people to know Zero Water was the brand, hence the quotes. It does initially run at zero ppm, but the amount of water I require (I have an HX machine which not only uses the water, but requires a purge, too), I don't mind running it until about ten ppm or so. I remineralize to around 100pm with buffer and magnesium.

Is this all getting all too technical to put water in to a coffee machine….

Am i going to be crying next year when my machine grinds to a halt.

For an easy life mine is plumbed in from the mains to the machine passing through an everpure claris ultra cartridge on the way .

Have i oversimplified it? Is there a difference to all the RO technical stuff ?
