I have a kinetico model 60 with duel black tanks. my problem is the screws stripped on the clear rubber top, that has the adjustment screw in the center. after using a type and dye kit it cracked the rubber part and stripped the black base of the water softener head/valve. Im looking for a model 60 head for parts. I cant find a dealer online anywhere to get parts. also tried the local dealer and they wont answer there phone. please let me know if you have any parts.
