Fleck 5600 Softener to 5600 AIO

[Vanste777]

I have a 3 year old Fleck 5600 64000 grain (12x52) softener that I want to convert to a AIO. I've purchased gravel and 2 cubic feet of Katalox Light. I've also purchased the green and black "backwash only" piston, but I don't know if that's the correct thing to do. From what I read, I need the "blue" injector and throat set since it is a 12" tank as well as a 7.0 GPM DLFC button (please correct me if I'm wrong).

I can't find the air intake check valve anywhere. Do I keep the brine valve piston in place or does it get removed?

Any help would be greatly appreciated. TIA

The recommended Backwash rate for Katalox Light is 10-15 GPM per ft2. For a 12" diameter tank, that equates to 7.8 - 12 GPM drain flow, but since the drain port for a 5600 can typically at best flow only 7.0 GPM even with no DLFC button present, a 5600 valve would be unsuitable for a 12" diameter tank of KL media.

I can swap the tank out. What size do you recommend?

A 9 inch tank.
A filter piston could not be used for AIO. I don't know what all is needed to implement AIO, but AIO does use the brine draw stage to draw air. So a filter piston, which has no brine draw stage, cannot be right. And if there is no brine draw stage, there is no point to an injector. Sorry.

Would BIRM work in 12" tank with AIO?
