I've been eyeing the Berkey. Is there an Australian outlet or just the internet purchase?
Buy from US. It is gravity fed - which is an adv over a RO unit, but RO strips down to 2ppm or thereabouts. We bought the biggest, you can run it on just one black filter candle if need be (if you have an extra plug - ie seven holes need to be plugged with one using a filter), or the whole eight filters for a really really large group of people. We got the white after filters as well.
Will take four years to get our money back, but I am very happy with it. We have had an RO unit in the past.
I'd order some extra spigot rubber washes.
If you overfill it it will leak. You can buy a level indicating spigot for this.
Or to save money there are instructions to build your own, prob on youtube. You still need to buy the filter candles.
