ro/di decreased output

[thereeftank]

I changed the carbon filters in my ro system and now I have decreased output... maybe like 5gallons overnight instead of the 30 I used to be able to make previously. What gives? I dunno what to check or what to do. I tossed the old filters out. I don't think my water pressure changed (around 65psi). membrane is 1 year old.

There has been a post here couple of months ago describing the same issue. It turned out to be defective carbon filters. I would buy a set from a different supplier.
