Wondering if a TDS reading of 16-18ppm is alright. My tap water is absolutely horrid at 560-580ppm.
I just checked my TDS after the membrane but BEFORE the DI. Getting a reading of 36ppm. That works out to a 94-95% rejection considering feed water is going in at 560-580
Now looking at my DI closer, I'd say its close to 80-85% exhausted. I know I'll need to replace it, but am I depleting my DI resin prematurely with my TDS at 36ppm going in to it?
Whats normal. Or is this just "My" normal seeing my feed water is so poor.
I cant see anything else wrong, is 16ppm safe to use?
TIA
