FWIW, we definitely have RO machines at Kroger and Safeway in Longmont despite having water with a TDS ~50 coming out of the faucet. Form-factor of the 5 gallon jug has some appeal,  I guess ¯\_(ツ)_/¯

I take it that the tap water has either iron or manganese (metallic) flavor?

My tap water is crap. I got RO from the grocery for years.

Now I have an RO system for brewing. I figure a year break even, or so. Not having to lug 5 gallon jugs was what made this old fart pull the trigger, and I am happy I did.
I'm right about at this point.  Yes, cheaper to buy at the grocery store, but with a plumber friend willing hook it up it would save lugging 20 gallons home for 10 gallon batches (need to cover from HERMS coil).  I might pull the trigger in the next year.

Most large grocery stores have RO water dispensers and charge between 35 and 40 cents a gallon.

Unfortunately, not universally true. Areas that have low or really low TDS are unlikely to have RO machines in any stores. In essence, if you can't find RO machines in stores in your area, there probably isn't a great need for RO treatment and the tap water is more likely to be usable for brewing (of course, you still have to adjust it for brewing).

Makes alot of sense.  IIRC TDS of mine was 120ish/alkalinity is 90ppm and I don't really consider that good maybe average but it's better than many I see posted I guess.   

While RO water makes brewing easier it is no magic bullet.  Light beers will probably need more acidity and alkalinity for dark.  Best to learn BNW...

Thanks everyone.  My tap water actually taste good but it was the chlorine and chloramines I wanted to rid myself of.. Found this on amazon. https://www.amazon.com/gp/product/B007I6MN72/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1

Think I will give it a try. Through work, I have access to lab testing so think I will run some water through it and see how well it removes.

A small amount of sodium metabisulfite (campden tablet. Apps 1 tablet per 20 gallons) will remove chloramine in water. I am less certain about chlorine, but chloramine removal is very cheap and easy.

Potassium metabisulfite, not sodium... my mistake.

APEC Top Tier 5-Stage Ultra Safe Reverse Osmosis Drinking Water Filter System (ESSENCE ROES-50) https://www.amazon.com/dp/B00I0ZGOZM/ref=cm_sw_r_cp_apa_SPcQzbRMG4JZ0

works well for me, makes pretty much distilled water, from 450tds to 12tds

but slow

I have the Apec. Use it for brewing, drinking, cooking, plants, dog, etc. 350 ppm in, 14 ppm out---just short or 10 years into a 10 year RO membrane. There's much cheaper systems out there but with nowhere near the membrane life.
