I want to set up a permanent rodi holding reservoir that will fill itself. wondering how people fight tds creep from ro membrane and di resin.
out of tap 500+ tds
when i start the rodi i flush ro membrane for couple min.
then i let water run through prefilters and membrane and down the drain untill 4-5 tds
then i finally let it run through di resin but even that water comes out 1-3tds for first couple min so i also let that go down the drain.
Once it hits 0 i hook it up to ro reservoir.
so im worried if its always running to fill reservoir. How do people flush the ro membrane and what about first few min of 1-5 tds from tds creep.
not sure if im explaining right.
End goal is
1. 40gal ro reservoir automatically filling 5gal reservoir under my tank for top off. will do this through solenoid and float switch
2. awc that gets water from 40gal ro reservoir.
