Brass y fitting?

Like I said, it should be fine so long as it’s all before the filter. Personally, if I had the choice, I’d go with plastic/PVC (but I also don’t have copper pipes). So long as you’re checking the TDS of each batch of water, and changing all of your filter cartridges on schedule/when they’re depleted, you should be fine.

Well I got a pretty expensive rodi unit with a booster and TDS all built in hahaha so it should tell me pretty accurately!

It wouldn't degrade and take up as much di resin as you would think. I happens slowly, but copper in the water none the less. Copper is pretty chemically resistant to acids actually. It does happen slowly though.

Well that being said I think I'm kinda screwed regardless with my house being copper pipes. I'll just have to change my resin more often. Which is fine. All the copper and brass is before the RODI Unit.

Mines mostly copper pipes but usually around 9 ph water. I only have di resin for the silica and co2. I wouldn't worry about it. Especially if you water is over 7.4 ph. Only about 4 mg/L is soluble at 6.5 and about 1.3 mg/L at 7.4. Quoting a quick net look up but at alkaline ph it is really insoluble. I think for my resin it holds 38 grams. So that would be able to pass 29,230 liters at ph 7.4. or about 7,722 gallons divided by 2? Depends on the oxidation state its in really...lots of math... before it was full of copper lol. I wouldn't worry.

I love you for breaking it down that much. Thanks my man!

That math was for sodium. New math for copper of unknown kind at Ph 6.5, mEq of resin 1.1 = 2183.79788 gallons. Lots of variables but you will still have plenty of wiggle room. For cation resin. For mix bed resin about 1091 gallons.
