Linda, you would do best to get it repaired by the local water treatment people. Take a look in the local yellow pages.
The problem is that water softeners and reverse osmosis systems can be private labeled and ordered from the OEM (original equipment manufacture) just about any way you would like.
It’s not that your softener is a poor quality or anything like that. There are just so many companies out there and only so many OEM’s.
Chances are if it was purchased locally than you should be able to get parts locally too. Don’t pay more than $200.00 for any residential softener repair you can buy a great new softener for $450.00.
Finally ask a lot of questions you will find the right person just by calling around try a business that prides itself on being independent or has been in business for 15 years or more. Not all of us water treatment folk are snake oil salesmen.
