$18 HM Digital TDS-EZ Water Quality TDS Tester
Been testing my kitchen sink water several times today with my new toy:
Arrowhead Bottled Spring Water = 202 ppm
My BOISE Kitchen Tap Water = 62 ppm
My Culligan FM-15RA Kitchen Faucet Filter reads the same as my Tap Water.
Important that all test sources be room temp. It appears that my Tap Water is just fine and I have been wasting money on the faucet filter The weird thing is the faucet filter gets reduced flow after every two months requiring regular replacement.
must be the visible rust?
