TDS before ro membranes

[cleaning up mud]

What is the tds of your water after softner but before the RO membranes? Just wondering what other cities are.

 

[WikiWash]

I do not soften my water. Before membranes and charcoal filter I am at 37ppm TDS after membranes 0ppm TDS.

I test about 110 ppm and 4-5 grains before softening. Zero grains after softening. After membranes I am like Wiki...0 ppm TDS. At least that's what my meter says!
