just got my new ro system 200gpd from ro man
the tds has started to creep up from 4 it's now on 23 from the ro unit, is this normal as i've only produced about 180 litres?
also the inline tds meter that came with the unit gives me a diffrent reading from my hand held one the inline one say's 23 and the hand held one say's 30 is one faulty or do they all read abit diffrent?
