RO/DI Question

[sgarron]

Just got my ro/di unit from air, water, ice. I threw out the first 5 gallons and then tested the next cup, it is 0.00. Is it ok to use or should I run it some more?

run it some more.. wait for it to read 0.000000 just to make sure it is pure


If you are getting readings of 0.. use it!

It's also worth checking the calibration of the TDS meter, if possible. I'd follow the manufacturer's instructions very carefully.
