I've been looking at ideas for an RO water storage tank and wanted to see what you guys have come up with and how it has worked out....
I brew 5 gallon batches, so am starting with slightly over/under 7 gallons. I have an undersink RO system, so I bought eight gallon jugs of RO water to start out, then after the first brewday, just refill the jugs and store until the next brew day.I've been looking at ideas for an RO water storage tank and wanted to see what you guys have come up with and how it has worked out....
Can you provide any sources for this statement? I don't believe RO or distilled water to present any problems for the chromium oxide layer of stainless steel.Here's a tip, RO water is very polar and if you are putting directly into a stainless vessel and not brewing the next day ,you should treat it with the salts for brew day,otherwise it will strip the passivization off.
So my overactive brain came up with this solution to constantly have ~20 gallons of RO water “on tap”. I took a Gray Rubbermaid Brute Trash Can (NSF 2,21 rated…. Meaning food safe) added a SS ball valve to the bottom, plumb a float valve at the top and just T off my water line going to my small RO tank. I can just go straight from the ball valve into my pump and pump straight into my kettle on brew day. I can also fill water jugs for whatever purpose as I’ll always have RO water on tap. Any thoughts are certainly welcome…
I dont follow. Why are you adding yeast and sugar to your kettle before you brew?I plumbed my RO permeate line to terminate next to my kettle. I snap on a QD hose, turn on the water, set the timer for 2.5 hrs, and come back to a filled kettle when bitchin betty tells me the time is up. I prep my yeast and sugar so when the kettle is full I can add it, put the lid on, and I’m ready to brew the next AM. (I add Brewtan B to the deaerated water before strike but I add brewing salts and Ascorbic Acid to the milled grain in the mash tun).
When I do collect water I just fill gal tea or milk jugs. I use it in the coffee maker, countertop ice maker, ice tea maker, and humidifier. I also give it to my cat. I collect a cpl gal at a time for those uses. It lasts a cpl days or so.
So I think you are exactly right.... I thought of that, and I think if I put an inline check valve into the line going to my trash can, that should eliminate that... Or I just have to wait to use the faucet until the trash can is full again.... Great suggestion, though...The only issue I can see with this is that your RO tank likely has a pressurized rubber bladder in it(at least if it is a small undersink unit) that is compressed up to line pressure as the RO system filters water and puts it in the tank. If you have the valve open to the trash can, until the trash can is full and the float valve closes, there will be no pressure at the faucet from your RO system.

Come to think of it, if you could find and inline valve for the line to the trash can that would only open at or near line pressure, that would maintain the pressure at your faucet.So I think you are exactly right....

This does make sense. Water's polarity is an important player in the erosion process--it's a polar solvent-- and ultimately the formation of sedimentary rocks (geologic time). RO water has very little dissolved material left in it and hence lots of possibilities to dissolve material. RO water is neutral but would be picking up some CO2 as it sits as well. I'm not sure how fast that happens and I am not familiar with the strength of the bonds involved in chromium oxide nor its rate of formation to recommend any needed actions. Adding the brewing salts to the HLT would reduce the ability of the RO water to dissolve other molecules however. I am thinking however that SS would be kind of useless for tubing if water could rapidly deplete the chromium in the SS. While not RO, a source of city or well water would still have the capacity to dissolve the chromium oxide and in any flowing water situation that would make SS a poor choice for tubing as it would rust. Pure speculation on my part though.Bobby, I put 5 gal in the BK and 8 gal in the HLT and got called away to make venison sausage. 3 days later and my BK was so clean it even took off the blue ring from the induction burner. At the next MBAA Milwaukee district meeting I brought this up and collectively they told me to repasivate and in the future to add the salts for that brew to the liquor rite away.

I like that you give some to your cat! my cat requests correction demands ice from the ice machine when we get some fair enough!

Interesting. Guess your getting nutrients for the final pitch too.to deaerate the water in an effort to reduce disolved O2 in the beer.
