Truly it isn't faulty. I just got a TDS meter and it's over 1000 ppm coming out of the tap from my well. When I checked the TDS in my tank (which is 50/50 well water and town water) it was 700. My town water (haven't checked the TDS) has a GH of 1 and a KH of 7. I used the same kit as I did for my well water, so I think it's accurate.
