I've got a Fleck 5600 softener with the most basic timer available that I installed after having a new well drilled (approx 3yrs ago). The water from the well is awesome, just slightly hard. In fact, you can drink it straight out of the ground. Due to my own idiocy, we had some issues with it not using salt because I installed the whole house filter on the outlet side, not the inlet side (I had a reason, but it was a dumb one) so periodically I would have to take the valve stack apart and clean flecks of rust and junk that were deposited in the piping from the old well (a really nasty water source). Anyway it would work and we'd have wonderfully soft water for a while - it worked so well, that I just set it to regen once in 12 days (the max on the timer). Now the thing isn't using salt at all in spite of multiple regens per week. I've been through the valve stack (I stock the repair kit) multiple times, cleaned the screens, the orifices and checked the brine tube. I've also dumped the salt tank and started over there too, as well as inspected the float valve which was stuck. Now the stupid thing sticks all the time! A gentle push down and it will pop loose, but the next day it seems to be stuck again! Is this my problem? Do I have another issue? Maybe a defective installer lol?? This thing is dead simple but I'm at my wits end!
