Our 16 YO Kenmore softener looks like getting tired. 3rd time I had to
install main valve seal kit, rotor disc, and venturi valve kit.
Expecting a replacement next, any suggestions/comments? Our water
hardness is 15 to 20 depending what time of the year. 3 in the family.
Fleck? Clack? Autotrol? I don'r want Kenmore again.
