I have an Ecowater Systems Refiner, Model 3000 R20, that had overfilled and was leaking. I pulled it apart to inspect the rubber O-rings, clean the hose, and to inspect for any additional damage. I have put everything back together but I am unsure about the large metal gear. The gear has 5 notches that opens a switch and each is labeled with a letter (F,S,R,W,B). Can anyone tell me where the letter should be in alignment with the switch? Currently it is set to "S" and I hear water running, but I am not seeing much difference in water levels. Any help is appreciated.
