No Chloramine in San Antonio water

[BuckeyeHydro]

For those of you who might be wondering, I had a chance to check on this yesterday. The 2008 water quality report for the San Antonio Water System report shows chlorine (no chloramine).

The SAWS service area is shown here: http://www.saws.org/who_we_are/service.shtml

Just when I think you can't be any nicer. Wow, thanks for passing that on and thanks for everything you do to help us out, Russ! Have a good weekend.

[Bill S]

Yeah, Russ, I called them JUST TO MAKE SURE, right before I ordered my unit from you a couple of weeks ago.

[Sachuncpawnut]

WOW this sounds great. Have never been to San ANtonio and have always wanted to go there. Furthest we ever got in Texas was a trip to Dallas a few times. Yo wold think with Denison only bein about an hour away we would have gone to Dallas more.....

[txav8r]

WOW! talk about going the extra mile! Thanks Russ!

[BuckeyeHydro]

UPDATE: The SAWS 2012 report likewise still shows no chloramines - only chlorine.

thanks for the update russ!

New Braunfels DOES have chloramine in case anyone's wondering.

[alton]

So does Green Valley

Heh, I just ordered the chloramine cartridge too. Guess I should have done this first.

FYI, here is the updated link to the water reports: http://www.saws.org/your_water/waterquality/report/

Bexar Met used chloramine, and SAWS bought them out. As far as I know, SAWS still doesn't use chloramine in their own built systems.

For some reason I go through DI resin like crazy. I usually make 40-70g of RO/DI at a time. I'll burn up a half cartridge of DI resin in 40-50g. My membrane is 96% rejection rate and I've verified this with a tds meter. 274 in, 11 after the membrane and 0 out. I have the flush kit that I use every time I start making water and I leave it on for at least 10 minutes. I have no idea what would be burning up my resin so fast.

I am having almost the exact issue as Ben. New RO filters, new membrane. TDS after ro is 19, 0 after DI and the DI is spent in a week (50-60 gallons). No clue here either.

Are either of you processing water with chloramines?
Do you have high CO2 in your feedwater?
Do you have your system set up such that it turns on/off frequently?

I'm not sure how I would process water with chloramines.

My pH from the tap is right around 7.6 to 7.7. I wouldn't think that that would indicate an abundance of CO2. And no, I only make water in big batches. I already know that smaller batches will burn up the DI resin quicker due to tds creep.

That may be my issue.... I have my RO line straight to my sump. So it is constantly on/off. I will get that corrected this weekend, as I already have everything to setup my ATO, just been lazy. Now I have a perfect excuse to get it done ASAP! I will get it done, and post an update. Thanks Russ.

Either you have chloramines in your tap water, or you don't. Are you on city water? What is the name of your water utility?

I'm on San Antonio water main system.

We don't have chloramines Ben.

Which brand DI are you using? I started out with BFS when I got my kit, I had nothing to compare it to. I tried BRS once and it went super quick, around what you guys are saying 60~ gallons. Back to BFS and it lasts a ridiculously long time for me. I change it every few months and I make at least 25g a week.

Thanks, I will have to get some resin from them.

I will have to use the rest of my BRS resin, so it will be a couple weeks before I place an order. Do we get a maast discount? And do we have to use a code?

Thanks

And just for clarity, I replace my DI once TDS hits 1, I might make a batch or two with that but I try to keep DI on hand when it creeps up. I'm around 8-10 TDS after RO.

It also doesn't hurt to flush out the lines after the membrane prior to making water. Depending on your kit, you may have a valve to supply RO water for drinking. I sometimes open this and flush the lines into a pitcher so I don't get that water into the DI. I don't do this very often, though I mean to.

[JerryD120]

Those are good tips that I will have to apply. I never thought of flushing the system before sending it through the DI when making top off or batch water. I do flush when I replace the filters before sending it through the di though. Thanks for the info, will keep that in mind.

Yes, Robert. I've been using BRS brand color changing resin.

As Russ noted, systems that turn on/off a lot, you get a TDS "leak". The RO/DI should run for long periods of time, otherwise you will be putting high TDS water (for a short period of time) through your DI.

For this and several reasons, do NOT run your RO/DI directly to your tank/sump with a shutoff. Run it to a storage tank of some kind, and THEN run a topoff to your tank. Periodically, fill up the storage tank.

Just so u guys know. Legally it is likely that's SAWS would not have to alert anyone when they started using chloramines. They are most likely under no obligation to report it until the yearly report ( if even at that point). So just know any day any time they could switch. Don't want to scare y'all but it's important we are aware.
