Hi, just put in a brand new ro/di unit and went from 340 tds to 6 tds. is this normal? thought it should be 0 tds. also just a trickle/ drips come out of di line. is this is a normal flow rate? 75 gpd ro filter maybe i just expected more flow.
how long has water been running through the filter?
slow trickle is pretty common, usually do to poor pressure in the house, you can always buy a booster pump to get better pressure.
