Title: TDS
Post by: Wrekin C S on October 07, 2009, 07:08:10 pm

Hi

I checked my Water earlier and my TDS reading was 005ppm

So I changed the resin - still 005ppm

So I changed the filters - now 002ppm

When I do this it usually drops to 000ppm

Straight out of the tap 440ppm usually around this mark

Do you think my membranes are on there way out?
