mines an inline twin one so i check it everytime , first i put the ro on flush as its usually is high before flushing.
Tap tds - 250-300
flushing tds from 120 ish goes down to 25ish
once flushed it goes back to the normal 25 and i go from there, it works well - whats wrong with an inline?
i set the two pins that go inline accoss the t peice, i think thats how there sposed to be.
the in tds reading is allways about 250 the out varies because when you turn the tap or pump off, and its stopped working, it takes a while to get down to the best tds again, i usually flush it for 5 minutes, and it goes from over 100 down to 25 on the out reading.
