    Water Filter.. to refridgerator to use for espresso machine

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    hi, As per the title. Looking for what everyone is doing for water filters. Our water is quite hard here. South West WA. I'm currently using bottled water as recommened by Jetblack the supplier of our machine.
    We've just ordered the Fisher and Paykel Water & Ice fridge. RF610ADUX5. Have the plumbling piped in ready for a fridge with water plumbing. But no tap etc. yet. I was thinking the simplest way to get filtered water for the espresso machine might be to filter this tap and then use water from the fridge tap to fill the machine. What would I need? For those who have added a softening filter did you consider doing this? I've seen mention of a resin based filter( i think thats the one that you flush with salt water once a month or so) but would this be often enough with a adult son living at home who will go through any ice in the fridge as fast as it can be made and like me, loves chilled water. ( he will be in heaven) Or would another cartridge type system be more efficient and work out less expensive in the long run? Looking for information on what others have done.


    I've had a quick look several times at a few threads, but it's a bit mind boggling. If I can get some simple non tech idea from some of the CS members then i might have more idea of what to ask about in a sponsor quote email.

    Thanks

    Talk to Bombora, you can send them some of your water to test and they will recommend you a system. In case you don't know already the type of filter you need for a fridge system like yours will be completely inadequate for a coffee machine. Depending on how fast you go through fridge water it may be more economical to have separate systems, or even keep using bottled. Bombora should be about to answer that too.

    Iím going to be in a similar situation within a few months.

    One thing I know id prefer having the one filter over numerous systems.

    having another look the outlet is ready to attach to the fridge now. I might just do that when it arrives on Wednesday and wait until I'm on holdays and get the filter sorted then.

    I akso did a bit of research on water quality. We kill a hot water heating element ( the hard water version which costs more) in under 2 years here. We built this place 11 years ago and have been though 5 of them so far. 'because our water is so hard" however I checked into the Water Corps readings most recent data available for here and the claim is 65-120 PM. With an average of 98. I did a water test yesterday and looking at the colour chart it was closer to 50 Isn't this an acceptable range anyway? I'm now totally confused.

    Yeah I've done this, for the same reason - I was putting in a new fridge (F&P) with water and ice supply. I had to run the tubing around behind where my coffee machine was, so took a T-piece joiner off and fed it up trough a hole in the bench (right in the corner of 2 walls) and into my Expobar Minore. I've got a tap where it exits the bench and then a float valve installed on the top of the water reservoir. Its a tight fit for the float valve and the cup tray, so I keep the back end of the tray slightly higher so the low water tank pressure sensor can still work.

    As the OP hinted at, the standard fridge filter will NOT help water hardness. So I also use the resin ion-exchange filters on the end of the inlet line inside the tank of my machine (not part of the fridge filter system). I have relatively soft water so can get away with switching them out every 3 months (I'm also the only coffee drinker in the house). I have four of them and then I recycle them (re-exchange the ions in the filters using a salt bath) at one go a couple of times a year.

    In my case the fridge is nowhere near the coffee machine so this won't be practical. Plumbing was installed for a water fridge when we built 11 years ago. ( builder/plumber accidently added it... Which I didnt mind at all) Given the amount of water that will go through the fridge I'm wondering if sticking with botted water might be the smart move.

    I have similar setup. I put a ap115 filter to the cold tap in sink. After the 115 but before the sink tap is a t piece that runs to a resin softener. The softened water runs up the wall cavity, across the ceiling, down through pantry, out pantry at floor level and into fridge. So I fill my coffee machine tank through the water outlet on fridge, and my ice cubes are awesome soft water for the scotch.
    Eventually, I will plumb the machine with one of those little float switches mentioned above

    I don't believe Perth water is as hard as we think. We have a bit of rain in the dams (soft), and the desalination plant has been outputting to the dams also (soft). It's only the cleaned up ex gnangara mount ground water that is hard.
    I think the further south of Wanneroo we are, the softer the water

    I'm in the SW where most is ground water not dams.

    A long time ago I wrote a project report on ameliorating groundwater in that area for one of the bigger local wineries. If I recall correctly the TDS values were pretty high, up to 500 or so, which is too high for vineyard health.

    We were going to install a big RO but we couldn't get permission to dispose of the retentate (we wanted to pump it to the sea).

    Thats a valid option. When confronted with not being able to attach an inline filter to the mains water I looked at other options including RO. RO has 2 issues: the amount of “clean” water is less than the amount of waste, and disposing of the waste water. The best yield I saw was for 1 litre of clean water, I had to find a way to safely dispose of 1.25 litres of waste. Having a septic tank made the challenge even greater.
    Given the low volume of water used by the coffee machine, say 8 litres a week, using prepackaged filtered water seemed the best option.
    I went a little further and make up my own brew using the “Pureau” water, and adding Epsom Salts and Sodium Bicarbonate.

    RO systems with a permeate pump will get you a better ratio than that.

    Spoke to our local plumber while he was installing the charcoal filter to the fridge water and who also happens to be considering buying a machine. he's eyeing off a gaggia... I believe. anyway.. he said our water is borewater here. around 400PPM... Seems, just like me, his main reason now to plan on doing it soon is he is also saddened our/ in common, fav local coffee shop closed and he isn't keen on any of the others around here. I mentioned a site sponsor to get his water tested and to look at a proper filter to suit. Prompted him about this site. Seems he's been here b4 but got lost in the mountains of threads.
