My Fleck 5600 softener valve is acting up again. In the past, I've had to replace the thank valve because it got stuck in the spacers and broke. The symptom was continuous draining. This problem is a new one. The brine tank is completely emptied of water and I discovered yesterday that the softener puked out a substantial quantity of the softener resin through the drain hose into the street in front of my house. I swept it up as best as I could. But obviously, something else has gone off on the softener. I think it's some of the refill flow valving on the side that connects to the brine tank, as those components have not been serviced previously. Anyone have any insight into next steps?
