My softener is only about 5 years old and seems to have stopped working right suddenly. I inspected the brine chamber and noticed the float was stuck at the top. Not sure if it is the culprit or not, but I broke it free and am now wondering where this bottom "stopper" is supposed to be on the rod.

The part I circle in red is in question. It is pushed all the way down to that plastic washer. Should it be slid up, and does it matter how far.

Note I already set the top stopper to the 10 inches recommended.
