RODI not removing Ammonia?

[Hawaireefer]

I have a question about RODI filters. My tap water tests positive for 1 ppm ammonia, and so does my RODI water even after I replaced and flushed out the filter. I am detoxifying it with prime, but don't want to keep doing that (does prime even actually detoxify?). Does anyone know why, or how I can get rid of the ammonia?

When was the last time you changed carbon blocks or the di resin? Anything that got past ro membrane should be absorbed by the di.

@Randy Holmes-Farley does carbon block remove amonia. Does chloramine show up as amonia on test kit.
