Son has a old Kenmore water softener which I believe is worn out. Been in his house for about 20 years. I don't get the soft water and suds that I get at my house. Am I correct in believing it is worn out ?
Next question is do I get a good high dollar system from the local place or Colligan, or do I get another Kenmore or other water softener system from Home Depot or Lowes ?
Thanks.
