Do you trust your RO/DI too much?

So unless you change your carbon frequently in relation to the amount of chlorine/chloramines that is in your municipal water....or unless you test, you should not be sleeping snuggly at night.....
Muwahahahahaha!
Go test for chloramines/chlorine in your RO/DI water.
I read this and start laughing, then I read the responses and laugh even harder.
I love it when people overlook something obvious... Then you bring it up.

Are you laughing at me....

Mine wasn't available, but I emailed a request some time ago and it comes in no time. My water is crazy contaminated... hence the 400-500+ TDS, I guess.

Laughing because you are cooler than everybody? I don't get it?

well, no, in my head, when I read your post, I got an mental picture in my head of Jaws as chlorine waiting to strike.
Plus stuff so simple, yet, such a brilliant point, makes me laugh. Because we all, (I know I did) overlook something simple as chlorine.
This isn't the first time you've posted something like this, that I though, why wasn't I checking this? I'm a moron.

I passed tap water through just a DI to test Chloramine removal.
Before = 1.2 mg/L
After = 0.0 mg/L
I used a Hach test kit.
%%

 

[cranberry]

When I get up I'll try that as well!

 

[cranberry]

It seems it does remove chloramines, however the chloramine removal effectiveness may be reduced before the DI shows that it needs to be changed.

 

[bang guy]

About 10 years ago I added another carbon stage because I'm paranoid about forgetting to change carbon and killing my RO membrane.
Not a bad idea...

 

[aquaknight]

Well the kit finially arrived today along with all new filters. Interesting/easy test, but a little disappointed that there really isn't any 'real' levels.' The amount of chlorine or chloramine you have is based on how pink the water turns. I guess with a duel test, it not possible.
Anyways, I was safe. My carbon was way overdue for a change. The left is tap, the right is out of the DI on the old filters. Seems like I have a lot of chlorine or chloramines.

How often do you need to change out the DI resin to make sure its removing 100% of Chlorine and Chloramine? I used the color changing DI resin, do I wait till it fully changes color?

 

[daftboy]

i use tap ... *flame suit on*

The carbon stage needs to remove all chlorine. Otherwise your RO membrane will dissolve.

 

[coral keeper]

I know, but, how often should I change the DI resin?

There really isn't a timeframe like for the RO membrane, with the DI resin, it would be by TDS readings. I let mine get to 3 TDS before it's time for a change. I always use coloring changing DI resin, though haven't had the cartridge completely changed before I got 3/4 TDS.

 

[cranberry]

I change when it hits 1 myself. I don't know what's getting through through.... but it's "1" of something and I don't like the unknown.

 

[mrdc]

Interesting thread. I think I will get a test kit for the chlorine and chloramines. I saw the filterguys test kit and was wodering if there is brand that might be sold locally in most areas. If not, I may look for the one posted online.

 

[coral keeper]

Do you calibrate your TDS meter that's on your RO/DI filter Cranberry?

 

[cranberry]

No, I don't calibrate. I use 2 inlines. I have found over the years, that if one remains at zero and the other starts to stray upward, it is usually the upward one that has gone bad. When I buy a new one, to replace the upward one, it always reads zero.
Those little Jungle test stripes are also very accurate when I've tested them side by side with the filter guys.
