I was looking at:

Reverse Osmosis Water Filtration System for Home

600 gpd. means 0.42 gal/min., which seems workable. The thing that worries me is that it looks like they use proprietary filters, so if the company goes **** up... The other thing that worries me is that they don't spec. a TDS after filtering.

(Sorry for the thread hijack. More on topic: I also cart a dozen single-gallon water bottles through the grocery store, and feel like I'm a survivalist who should also be stocking up on dried goods and beef jerky.)

Definitely recommend sticking with systems that use standard cartridges to provide both the best possible pricing and flexibility (like if you decide to upgrade an element like the membrane from one manufacturer to a better one). Competition matters!

Cheers!

My experience with RO water from Wal-Mart is that it tasted salty compared with the RO water from other dispensers in the area. I have five businesses with RO dispensers in the area to choose from and use the four that aren't Wal-Mart.

If you're filling a rig with 20 gallons of RO the typical small pressure tanks that come with most kits really don't help that much...
But you can start collecting RO water, in a large enough vessel, a day (or 2) before brewing.
You need to make your yeast starter too a few days before brew day, so just plan your water too.

Or you could get a large enough pressure tank, so you can brew any time at will. When the tank is full, the RO system will stop generating automatically.

Of course all of that is possible at cost plus space, but given I have the tiny tank for faucet duty and can put 20 gallons in my rig in under 5 hours - without using any of the stored RO in said tiny tank - that's good enough for me...

Cheers!

@Buckeye_Hydro, looking at your systems... wanting this for brewing only, do I need a RODI system or would a RO work fine. What about the Chloraguard Stage? Our water service does add chloramine at the level of 1.8 annual running average, whatever that means... Thanks

RO only - not RODI for this purpose.
You'll want to add the chloramine option.

I can feel people looking down on me as I lug 15 single gallons to the front.
Jeeze all this time I thought people were looking down at me because of my "DEPLORABLE" T-shirt, I never thought anyone would care what's in my cart.
I'm lucky that the town water here is pretty good, but I do buy distilled when brewing lagers and IPAS and I'm making water adjustments.

This is a topic with the reef saltwater tank community where the stakes are much higher due to the sensitivity of very expensive corals. Are a reef hobbyist, thus crosses over to my brewing habit. Here are some thoughts.
to repeat myself, small amounts of trace elements can wipe out tens of thousands of dollars of livestock in coral reef tank so the hobby takes this most seriously


1. many reefers report success with walmart RO water. While RODI (Reverse Osmosis Deionized) at 0TDS (zero dissolved solids) is the standard, the Walmart RO is sufficiently low in TDS to use in a reef tank.

2 while a full set up is good, a portable unit under $100 that hooks up to a kitchen sink faucet or a washing machine connection is all you need. I have one such unit that is rated 75 gal per day and I make 5 gal of rodi @ 0 TDS in about one hour each week. Keep in mind this is RODI at 0. An RO unit should be faster.

3. if you have hard water you can add some cheap pre filters to the unit to ease the workload of the RO chamber. Saves you money and time.
.
4. Spend a few dollars for an inline TDS meter. They usually are an option with the unit but can be easily added to an existing unit. It takes the guessing game out of when to replace cartridges. I have a dial probe, one just before the DI and one right after so I know how both my RO and my DI are doing and because it’s for corals know precisely the TDS.


with my cheap unit and making 5 gals weekly and an extra 5 gals monthly my unit goes a little more than a year before needing to replace my cartridges. 3 years on the more expensive on (off hand I can’t recall if that’s the RO or 5he a DI)

Summary, Having a unit in the house is a game changer for ease. You don’t need to spend more than $100 for a suitable unit (my TDS meter confirms this). Walmart is reliable if you don’t mind lugging water home.

Fwiw, my local water is fairly neutral. I use the mid points of the most recent water reports and add the salts to reach my desired water profile. That results in, IMHO, extremely good beer, if I do day do myself. Mind you I have Clean slate water on hand to start with on brew days but I find it easier to use the tap (and the calcium sulfur mg etc that comes with it) and adjust accordingly. It’s not precise but I am not going to argue with my taste buds especially if they tell me not to make for extra work.

Hope this helps.

It may be a regional thing, but I've never actually seen an RO or distilled water dispenser in any Walmart (or any other grocery store) around here. They do sell 1 gallon jugs of distilled water for 82 cents each.

I recently decided to jump in to water chemistry. Our city's water report was useless for brewing water info, and contacting the water department was even less helpful. Our city water supply is drawn from 3 different reservoirs throughout the year, which would require 3 separate Ward tests and knowing when the sources are switched. I considered a LaMotte test, but decided to just buy an RO system for home.

Even if I could locate an RO dispenser, having an RO unit at home is way easier and more convenient than lugging gallons of water home.
