Input TDS reading of 003

[johnsonw2]

I purchase a 75 GPD 4 stage RODI unit from BRS back in December. The unit came equipped with a TDS meter and when i was first flushing the unit the TDS meter read 020 ppm then slowly decreased to around 003 ppm. Since then i have been using the unit about once a week and my input usually reads around 003 ppm then even drops to 001 ppm. My output water has always read 000. I know its normal for input readings to be 400+. Anyone else with a similar experience or could my meter be faulty? I live in Ocean County, New Jersey if that means anything. Thanks

If your input reading is .003 then you really don't need to use the RO unit, unless you have phosphate in your tap water.
