Fedex brought my ro/di unit to me today... I've got everything hooked up temporarily. I've got a question or two though.... my psi reading is on the low end about 32psi, and my tds readings from tap is 40ppm and the product water reads 0ppm, I'm guessing that the unit is in fact working, but the thing that has me wondering is this... I barely have any waste water, maybe a drip every second and a half or so, and my product water is flowing very quickly. I filled a 15 gallon tub in about 30 mins (its a 35gpd unit). Is there something wrong, or am I just paranoid?
