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?

Make only one post for questions. It will eliminate confusion for us trying to answer multi post.
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.

The di is what mostly removes ammonia. Is the effluent 0 ppm tds?

When a di first depletes, the effluent can have even high ammonia than the incoming water as it is easily displaced from the di resin by more tightly bound ions such as sodium or calcium.
