I know that if water sits long enough within the RO housing, the TDS will shoot up as high as 100ppm, but my main concern is, are those PPM mainly dissolved various salts? like, no bacteria, or organic compound can be passed through the membrane, right? and so it is still better to drink the...

Hi, I recently started using a new 4 stage 150gpd ro unit - I am on well water that is about 7.0 ph and 120-130 ppms on the .5 scale. Water is coming out of the membrane at 50-60ppms with new filters; membrane appears to be properly seated. This is not creeping tds issue it has been like this...
