yea something is definitely up with the seals/spacers as the rapid rinse has slow drain flow. It is almost like brine draw and rapid rinse needs to swap places or is leaking in the wrong spot.The highest flow to drain, is only during the Backwash and Rapid Rinse (sometimes called Rinse) stage of regeneration. For a 9" diameter tank, this will be typically 2.0 GPM, 2.4 GPM for 10" & 3.5 GPM for 12".
During Brine Draw (BD & Slow Rinse are combined as 1), the flow rate to drain will be low, often less than 1 GPM depending on which specific injector is installed.
If the flow rate to drain is high during Brine Draw, that can be another indicator of a worn or damaged seal.
