No, your tds after your membrane should be around 3ppm. Your membrane is working at 79% efficiency.

Whats you waste to pure ratio when you are producing water?

With 120ppm you should be fractional over 1 waste to fractional under 1 pure - 55% waste to 45% pure, perhaps 60% waste to 40% pure.

See if anything happens after a few hours of flushing your membrane?
