AK Q06 Why is my TDS not 0? My system is RCC7AK.

The RO system has a 90% reduction of total dissolved solids so it will never be 0. You would need to test your tap water and then compare the results to that from your RO faucet. You should also remember that the alkaline filter is adding back minerals which will show up on your TDS score and cause the results to be a little higher.
