My tap water is around 270 PPM so I was advised to pick up a filter (by members on RIU). I flushed the membranes this morning for 45 minutes and collected about 4.5 gallons of RO water.
The PPM came out to 70 but the PH was around 9+. Could my PH meter be defective (Dr. Meter PH-100)?
I doubled checked with the Ph UP / Ph DOWN liquids and the color came out to a very light green. The color matched the PH level of around 6.0.
Not sure which method of testing would be more reliable / accurate.
