Are ou testing for chloramine?

I am just checking to see who is checking their city water for chloramine and what you are using to check it.

 

Would I be better of with a Hanna checker or a standard test kit? Should I be looking to measure total chlorine or free chlorine?

You should be able to call your local water company to find out what they put in the water. Mine gives me a full report on request every year so I know exactly what is in there.

 

I don't know how you would test for chloramine though since it is just ammonia added to chlorine. Pretty much any municipal water source will have chlorine in it. Not many use chloramine.

I think chloramine is becoming more and more common because it's more stable.

 

Randal Holmes farley thinks most decent carbon blocks are capable of filtering out chloramine effectively, especially if you have two carbon stages. I opted to run a chloramine specific block in conjunction with a standard block. I've never tested for it but I've never had any issues.

The main thing with chloramine is a decent di canister because your ro won't remove the ammonia after the carbon breaks it's bond with chlorine.

Approximately 30% of the public water systems in the US are using chloramination.

 

Its not really that big a deal as long as you are using a high quality, low micron carbon block and you are protecting that carbon block with a 1 micron or smaller sediment filter so its pores do not become fouled or plugged redering it useless for adsorbing the chlorine portion of chloramines. As GHill said, a good DI filter will polish off the ammonia portion.

What do you think about the refillable DI resin from BRS?

That's what I'm currently using. Here in SAT TX, currently no cloramine is being used for the time being, at least last time I checked.

After trying resins from every major vendor I use only Spectrapure MaxCap and SilicaBuster resins in non color changing varieties. When I was using others I could only get around 150 measured gallons before starting to see TDS in my finished water, didn't matter the vendor and they were all supposed to be factory fresh and I was very careful about vacuum sealing it and storing it in a cool dark place as recommended.

I switched to the MaxCap/SilicaBuster dual DI and my first MaxCap lasted 830 measured gallons before I started to see 1 TDS. I replaced it and got just over 1000 gallons out of the second with the SilicaBuster still at 0 TDS finished water. The third MaxCap also lasted over 1000 gallons and the SilicaBuster just started showing 1-2 TDS so I replaced both. That is over 3000 gallons out of just 4 cartridges versus what would have been 20 cartridges or refills with the others. This was a no brainer for me and I have never looked back. I now have a Super MaxCap caretidge installed and once the SilicaBuster finally exhausts I will install a Super SilicaBuster I have in the refrigerator waiting to be used.
