Can a system like that adjust the PH of tap water?   

I have heard a lot of people in my area complain of things like IBS and skin complaints, and blame the acid water in the sallins and Johnstown area.   We buy gallons of drinking water in the household because of it.  200 euro seems like a   reasonable investment to prevent such ailments.

Irish water shud ensure water is ph neutral. Sallins water is 40 to 50 ppm and ph 7.5 today as i speak

I found this; https://www.osmotics.co.uk/products/3-Stage-100-Gallon-Per-Day-Reverse-Osmosis-System.html might be a decent one for brewing - decent throughput, cheap, and 3 stage should be enough.

Great thread lads,  anyone pull the trigger on one yet?

I picked up a 5 filter unit plus remineralisation unit and pump in Spain for €170 plus a full spare set of filters for €14. I'm on the way back up now and it's in the boot of the car. I'll probably take a tee off before the remineralisation unit for brewing water and use the other end for drinking. It's seems strange to strip all the minerals out and then add them back in, but I think it's something to do with the W.H.O.

Was talking to a few lads and they sound the business, its  now on my never ending brew equipment list

I think the idea of putting the minerals back in is that while stripping out all the bad stuff like lead, the good stuff gets taken out too. So the ideal solution is to remineralise the water after it has been brought back to h20

That's it. Remove everything and start with a blank canvas. It's much easier to add minerals then take them away so when your starting with just h2o it's easy with a calculator to get whatever water profile you want.

Also, according to a WHO report, if you drink just RO water, it will slowly leech minerals from your body, thus the reason you get a mineralisation filter when using it as drinking water.

Sorry I'm confused is that a good thing?, not sure I want to drink RO water, body needs minerals as well surely?

[nigel_c]

I've heard that about de ionized water but not RO. Haven't read up enough in it to know what the big difference is though.

[Leann ull]

No I was thinking for normal drinking water, drinking ro would be great if you were in an area with nasties from lead pipes or similar but human body need minerals from standard tap water?

You get a lot of salts and minerals from your food, more than you get from water. People throughout the world drink collected rain water which is fundamentally distilled water. You will need the RO water to act as a blank canvas for brewing, where you will want to add specific salts and minerals to build a brewing water profile. This is why I'll tee of before the remineralisation unit. The outfeed from the remineralisation cartridge will be fed to the drinking water tap. I'll have to research as to  whether the remineralisation is actually of any real benefit.
The issue I see is that the reservoir tank will be filled with the remineralised water, and I will need a seperate vessel to collect RO for brewing.

Watching yours and Nigels trials with interest, especially amount of water require to produce 1l, don't forget your Pegas

Apparently these units need to be used regularly so I opted to install it in the kitchen under the sink rather than in my brew shed. The trade off was I had to install another kitchen Base unit in the utility room to make space for the stuff that was under the sink. So finally new kitchen unit installed in the utility room and stuff cleared out. It fits like a glove. There's a small weep coming from the top of the reservoir unit. I reckon there should have been a seal supplied with the valve connection. So I have it left off until I can pick one up tomorrow.
