just changed filters and question

[jnb]

I just changed out my sediment 10, carbon 5, carbon 1, drinking carbon, and color changing DI filters - it has been 6 months or more - my RO is rated 75 gmd and is at least 2.5 years old.

testing:
was 0.6 from DI now 0.2,
Tap is 109.0,
RO is 8.5,
RO from tank thru carbon drinking is 20.1

I am surprised that it is making water so noticeably faster - is this common? - It seems faster than ever before.

I noticed my RO from membrane is 007 and after it goes to tanks and through the post carbon it reads 015. Why is this? Does the post filter add TDS or is it the tanks doing it?

yes, per this sponsor once when we talked - it just is picks up something along the way - it is normal
