I thought my tap water tasted pretty good. Its 225ppm. When i compared it to my RO i could not believe the difference. Will never go back although it seems a bit weird throwing chemicals into pure water to make it taste crap again. Yes they do waste water but still works out cheaper than buying it and also great for brewing.

Aye, once you've seen a 5 micron pre-filter after just 12 months you stop thinking of tap water as "clean"... Ours tastes foul anyway, smells nasty too!

I'm not sure which one it is tbh, it was given to me by a mate but I think it's the 50GPD. I have the screw on tap connector which I connect to the outside tap via the kitchen window. It takes a few hours to collect the water so I usually do it the day before brewing.

The 'need' for RO water for brewing is largely dependent upon your tap water. If your tap water is too mineralized for the beer styles you prefer to brew, then getting RO is probably worth it. But this isn't an automatic need for all brewers. There are plenty of water sources that are lightly mineralized and suited for brewing with only minor treatment. Finding out what's in your tap water is the first step in learning if you need to make the switch.

Before you go buying any filtration system, get a water report from your local supplier.

Here in Belfast the water has only 5-20ppm of impurities, Edinburgh is similar.

Remember also that the composition of the "impurities" give water it's flavour. The water here tastes OK but travelling the UK you can taste different area's.

Also there are simple DI filters that will do the trick which may be much cheaper than RO. You may go through more DI filters but if it's just for brewing then the expense will be negligible.

I created Bru'n Water to guide me with brewing salt and acid additions. There is a free version available on-line. I suggest that you review the Water Knowledge page on the Bru'n Water website to help understand the why and how of brewing water treatment.

GlentoranMark...are you sure those readings are correct....5-20 ppm are very low. Im not disputing it but those figures mean that there will be no Chloride/Chlorine....Floride/florine (sp) in your water and no detectable trace elements either.
Im only asking because I keep a marine reef aquarium and need to get my water to as near "O" as possible and a few reef keepers in NI have trouble with this.
Solihull (Servern Trent Water) before RO treatment 184ppm...after RO 6ppm after DI 4ppm

Top Tip...Always keep your RO system turned on, just at a slight trickle. As soon as you turn it off the membrane will not do its job.
I reall ydont recommend turning it on and off...This will just damage the membrane and allow (dirty) water through. Always test with a quality TDS meter. TDS meters are available on line and are quite cheap.
