My water softener drips INSIDE the drain hose. What's causing the dripping?

My Kenmore water softener drips from the drain hose into the home drainage system long after it's done cycling. The drain hose is located seven feet above the softener, and the home drainage system is the same height as the softener itself, so the end of the softener drain hose is the same height as the softener, also. I don't know when it was installed, as I purchased my home with the softener already installed. The model numbers on the manual are 625.348490 and 625.348470.What could be causing the dripping?

The rotor and seal have to be leaking to cause the drip you describe. I recommend replacing the rotor and seal inside the valve of your water softener.

If you will go to www.sears.com and select parts you can see a parts diagram of your water softener. Enter the model number of your softener and select the page for "valve assembly". The rotor is item 86 and the seal is item 67.

When you remove the rotor and seal clean the inside of the valve body with a soft cloth or paper towels. The seal kit will have a tube of silicone lubricant in it, don't put any of the lubricant on the seal. Seat the seal into the grooves inside the valve, then coat the face of the rotor with a thin coating of the lubricant.
