Hi, I have a FM-1200 also called Fleck.
I have verified all the steps and the flow looks all good. It draw the salt, it refill the brine. It rinse, etc..
I attached a very nice step by step graphic i have on my manual.
I don’t know the story of my softener, so once all the steps have been verified, I have proceeded running some iron out but still the water is hard (in and out has same hardness).
I then proceeded replacing the resin but still same problem.
I still have to verify if the by-pass is separating properly.
This o-ring caught my attention because i don’t remember to have seen it and i’m not even sure where it should be. I can’t visualize the position from the drawing.
I imagine it is the o-ring 11.
I have the 1” distributor tube with both upper and lower basket.
Low water piston.
Can you help to understand the position of this o-ring?
Am I missing something else?
i have seen that with a few hundreds bucks i may just replace this softener but would be a shame since even so has 25+ years, it looks still has a lot to give!
thanks
