how does one know if their water has chloramines. I just changed the filter of my rodi recently when the tds made it to 20. This seemed a bit quick considering i've used perhaps 700 gallons or so. I've looked at the city water report for chloramines and it does show some, but is this what people are saying is "chloramine" in the water?

Thanks.
Yes, your MUD uses chloramine to treat your water in conjunction with chlorine since both are present in the water. Most of Houston has now made the switch, even out to the burbs (I know Richmond and Katy both are using it for sure). NHCRWA covers a ton of area in Houston and has switched to chloramines, and many others have followed suit. Most of the time, you can dig up a "letter of conversion" from your MUD.
