Guys - Thank you for your help! I'm out of town for weekend, but will check sizing Monday morning, what I can tell you is Cedar Rapids water is pretty good they soften down to 8 gpg and no iron or other..
As far as what test I have done to say too much salt inlines after a regen, I tested using the hach hard water test and the reading was off the chart, never had that before... tasted the water and very salty, so salt throwing test way off, I continued to monitor the water usage by using the 7000 screen counting down the gallons used between the two, seemed to take roughly 500 per unit, before water testing 0 gpg.... I'm really confused as to why it would take that long to get to 0 gpg, I could understand possibly some but would think it would be flushed out fast or faster than dragging it out that much?
Programming from what I recall being in the unit a far as cycle settings are:
brine draw slow rinse 60
second back wash 5
rapid rinse (they had initially at 5) now set to 10
brine fill 12
last time out they did switch the size of something to a 7? I remember them talking about that...
