I'm having the same problem:
Over the last month or so I've noticed that my water after a regen is way too salty and I have to run the tap for a few minutes and then it's back to normal again. I live alone so no one is running the water during regen.
I have checked the black line running to the brine tank for air leaks. Have removed and cleaned the brine valve and float assembly. Removed and cleaned the small injector. Checked and cleaned the drain line and the fitting that it is connected to. All of these things are ok so I watched what it is doing during a regen :
1:11 it starts by draining for a few seconds then starts filling the brine tank from a low level of a couple of inches of water to about the 1 -1/4 salt bag mark.
21:20 on this twenty min cycle nothing seems to happen.
2:99 nothing happens I assume it is creating brine for the 99 min.
3:10 For these ten min it is draining to the floor drain.
4:17 during this time the brine tank is emptying and takes about 15 min to do so. Also it is draining to the floor drain the full 17 min.
5:4 It drains to the floor drain these 4 min and then it is done.
Can anyone tell me if these cycle times and what it is doing seems normal?
The water pressure to the softener is 20 to 40 psi depending on when the well pump comes on to fill the tank.
Any help is appreciated thanks
