My Culligan mark 812 softener stopped working. I've cleaned the screen in the valve, the pickup and fill tube seems to working ok, has suction and discharges water into the brine tank. So today I emptied the brine tank of salt and cleaned it. I'm 73 and don't bend like I used to so this was a little hard for me, so before I refill with salt I'd appreciate some advice.

The tank has a finely perforated plastic disk on legs which keep it about 3 inches from the bottom of the tank. The stack fits tightly through this disk with the intake hole just below the bottom of the disk. When the disk was removed the bottom of the tank was filled with a very thick salt slush. This doesn't seem right to me, shouldn't there be only salt water below the disk? Also, the disk has a series of flexible tabs around the edge that appear to be meant to function as a seal between the rim of the disk and the wall of the tank. A number of these tabs are missing and I think this has allowed too much salt to enter under the disk. I didn't find any of the missing tabs when I cleaned the tank, but they may have been hidden in the slush. Question; do you think this is the source of problem, and if so where would I get a replacement disk or any suggestions on repairing this one. Last question: what is the proper settings for the stops on the float rod that determine float travel up and down.

Hope this description makes sense! Any advice, suggestions or info very much appreciated!!
