Looking for an under-Sink 5-Stage Reverse Osmosis System

Looking to drink healthy water and WA water has a chloride smell and etc.

5 stage system with RO ONLY

Filter must be easy to find better UNIVERSAL or easy to replace, I’ve heard people ordering filters that’s from a 7 years system and that cost them $700

Must have a water tank for higher flow

If there is any recommendations please let me know!!

    • I don’t think it’s a 5-stage one

      • How do you know stage 5 is healthy?

        • I prefer this way

  • Ive had a 5 stage ro for 12 years, i recommend a 7 stage to add back the minerals lost in the filtering process. Without remineralisation i developed kidney stones at the 5 year mark.

      Why does it have to do with kidney stone if you haven’t had too much minerals? I don’t get it 😂

      Also that’s awful mate.

      • Reverse osmosis basically removes everything from the water, the good and the bad. It makes it distilled water.

        Thats what the doctor theorized, obviously no way to prove it except i started adding a pinch of himalaya salt per 4 cups of water, and it went away. So the doctor was propably right.

        • I would be happy to add salt instead of drinking water that way 😂

        • you mean lack of minerals = kidney stones ?

    • Magnesium is perhaps the most important, getting rid of cow's milk saved more people from nasty stones.
      Both mg and calcium are tasteless, only salts add taste, the cleaner the less salt one can detect.

      • Raw milk from cow is great for you

    Depends how good you are on DIY.
    Ebay membranes sometimes go near 10 bucks, gpd means US gallons per day, smaller numbers mean finer water with less flow and more need to backwash.
    Housing: around 20
    5mm tube check Robbert B.'s empire the 'bay it.
    Suggest to start with pressure reduction one way valve or to be perfect filter whole house against dediment, your flickmixers will live longer too.
    then 1st charcoal filter, then membrane and then tank then post charcoal polisher then in my case magnesium enricher (hard to find) and faucet. And also important is to deal with membrane flush: the 3rd port in its housing I put on a solenoid that periodically backwashes the membrane.
    I call it no taste water we cook nothing with tap water anymore.
    I used to be a soda junkie, now real water has lifted my health!

    I'm looking at getting a RO system soon too. Ebay seems to have them for less than $100, but I don't know.. they seem to all be reselling the same cheap chinese systems. No telling for sure if the quality is anywhere close to what you'd get buying each part separately. Not just contamination concerns, but quantity and quality concerns too.

    Ignore the water remineralization bs. Drinking water has very little minerals in it, as in thousands of a gram per litre. Unless you're doing heavy exercise, drinking litres, and also simultaneously fasting, it's unlikely to ever be an issue.

    By water tank I'm guessing you mean pressure tank. Those are about $100 on their own.
    And when you say RO ONLY I'm taking it that you want a carbon filter as part of it, because that's what removes the chlorine.

    You may also want to get one of these installed. They measure the electrical conductivity of the water, so you can compare whats going into the system to whats coming out to judge how effectively its working.

    (not from this site its just the first link that popped up. You can get them cheaper elsewhere)

  • I run a booster pump, town water is 20 PSI hardly enough it's now 80PSI and run parallel 75GPD filters. TDS is around 6-8 from 250 which is good enough for my needs.
    Started with a cheap kit from ebay last year for about $200 and built around it from Aliexpress probably another $250 on pump, computer, extra filter, flush soleniod ,ect.
    Just use 10" filters and standard RO membranes and you can't go wrong.

    • What is standard RO membranes?
      And how can I access 10’’ filters?

  • 10" filters you can buy and get ripped off at Bunnings if you needed it now. Buy anywhere on line 1/3 1/2 the price if you can wait.
    I bought this which is all standard fit. I'm happy with it. https://www.ebay.com.au/itm/233633640278.
    https://www.bunnings.com.au/stefani-1-micron-green-carbon-re… will fit this too

    Standard membranes https://www.aliexpress.com/item/1005002531936473.html?spm=a2…

    Best to get a TDS meter to know how good or bad you town water is. and get pressure gauge or ask a plumber what sort of pressure your getting. Below 30 PSI is not good, You'll get a higher rejection rate making the pre-filters work harder and take longer to refill the tank.
    My 2.8 Gal tank would hold about 5.5 liters before it's emptied. Without the pump to refill would take 30-40 minutes, with the pump around 10 minutes to refill.

  • From being into reef tanks for a while, the go-to guy for people who have $$$$-$$$$$ riding on it was this mob in tasmania:

    I made do with a 4 stage unit (020b) and it's been great, well, enough to never have troubled very sensitive corals in a grow out tank at any rate. You need to set yourself a calendar reminder for the really long term bits like the main Dow membrane and if you're serious about this you'll get a TDS meter as well.

    I don't think there is a way out of this that involves spending much less than $3-400 for something decent - you can spend less, but you're buying a "5 stage" that performs like.. who knows what? You're not going to get something that actually does what it says for as long as it says it will.
