I am at my wits end trying to figure this one out. I just bought a TDS meter to see how my RO/DI unit was working, which turns out, not for crap.
Manufacturer: Dvoneb Aqua 5 stage RO/DO
Unit Age: 1 month
Membrane: ?
Flush Valve: Yes (is in correct position)
Pressure: 58psi
Tap Water TDS: 220
After RO TDS (before DI): 86
After DI TDS: 109
I also tested the TDS meter with Distilled Water which read 000
Ironically, it tests higher after my DI unit? How can that be?
EDIT: I just found the problem. I was using a carbon filter inline. As soon as I removed it, levels dropped to 0.
