I had a Culligan Mark 100 water softener with a Soft-Minder meter installed in 1999 and it worked well for years. However, in early May of this year, we had a particularly bad power failure, where the power went off, came back on momentarily, and then went off again for the better part of an hour.

Our daily regen is set for 2:00 AM, and when we got up the next day, we clearly had hard water coming out of the shower. I checked the water softener (in our well house), and found the time was flashing at 12:00. Water was also actively pumping through the brine line. I unplugged the unit, plugged it back in, and I then went through the programming and found a number of parameters had changed, so I re-entered the correct information. I then went outside and saw that the dirt covering our underground gravel-filled pit (10'x10'x10') for brine effluent was very damp and somewhat collapsed. This told me that an out-of-whack regen had been going on for hours and had likely been pumping raw hard water through the softener all that time.

I went ahead at that point a ran a manual regen, but there was no improvement in the softened water quality. After another week's worth of automatic regens, there was an incremental improvement, but still nothing close to what we had before. I checked for salt bridging (had none), but I still went ahead and fully cleaned the brine tank. It has now been several weeks, and we are still not back up to snuff.

Before I call Culligan about this, does anyone have any suggestions or ideas? I hope I don't have a case of fouled resin or something else major going on. Beyond that, I can't help but think something went south, or at least got triggered with the bad power outage that happened last month.

Thanks in advance,
Don

P.S. I forgot to add that I now have a small "Regen" note under the time on my Soft-Minder meter when I press status. Maybe I just don't remember seeing that before, but I previously thought "Regen" was only supposed to show up when you were actively in the automatic Regen cycle, or, you had just activated a manual cycle (and not that it would otherwise show up if you weren't in one of these two conditions). Again, maybe this means nothing, but I thought I would mention it.
