I know there are lots of questions out there about this and I scanned to try and find an answer first before posting this, so if you know of a topic that covers this please let me know!
I just got a TDS meter and calibrated it to a 1000ppm solution. I then checked my tap water and the reading was extremely low - like impossibly low for tap water from what I expected. That value was a whopping 15! As far as I know this house doesnt have RO or any other type of prefiltration. I also cant find any info about a multiplier being used in the results where 15 might = 150. The refrigerator water has a carbon filter and that reading came out to 11. Is this possible? Or is the meter junk?
i saw in the Q&A someone asked a relatively similar question and got a pretty obtuse answer that I am too dense to understand this morning.
