Does anyone know anything about RO systems, the seam to range in price from $300 to 1k, I'm looking at adding an under sink system into my brew room.

Ive got a boss 020 for about 3 hunge Mark and it makes the best water :handgestures-thumbupleft:
but with only 45 Psi mains Its incredibly slow :handgestures-thumbdown:
So I hooked it up to a pressure pump an now makes around 200lt in about 12 hours and I would waste about double that but I send that to the garden :handgestures-thumbupleft:

Plenty of good RO units on fleabay mate.
You can get great units for under a grand that other suppliers have quoted $10k for. For most users ~$300 is going to get you a great rig.

Depends on your starting water quality.
If you are feeding potable water from a city water supply you aren't going to need a massive sediment filter for instance, just a 5um prefilter would be ample. Then a carbon filter.

Something like this mate: http://www.ebay.com.au/itm/310789084679 ... EBIDX%3AIT

that looks pretty good, do you know what the difference between that one and the ones with the bigger round storage tank

The pump is cheap to buy on it's own. You get a few extra filters in the 7 membrane version so pressure drop is going to be much higher, necessitating the need for the pump.
At least that's what I'm thinking.

I'll be getting a system very soon myself, likely this: http://www.ebay.com.au/itm/310789084679 ... EBIDX%3AIT

I got mine from Veba's aquariums in Fremantle ,to make sure I could get replacement filter's and membrain's easily ,you may need some extra line and fitting's,I got a tee fitting and a tap end fitting ,so I could have an extra line out to a large storage tank (60lt fermenter).and some extra line for ya waste water.cheers hillzabilly
