The DI chamber in my BWI 75gpd 5 stage system has never filled up since day 1. I get 0 TDS out so I don't sweat it. Sometimes it gets about half full after I've opened one of the pre filter housings or if I've run just RO for drinking water for a while. Doesn't take long to almost empty out once I start running the DI again though. I've read a few posts here and elsewhere with similar info, some saying it's normal. No clue how it works, but like I said, TDS 0, why worry?
