We have an eight year old Superior brand water softner that has
started leaking water and salt from somewhere around the bottom. We
have not yet determined where it is leaking.

It is a single tank model that has an electric clock that controls
when it regenerates. It is made mostly out of plastic. I could
send a picture to anyone who wants to see it.

It sounds like it might just be a leak in the brine tank, so maybe you
just need to buy a new brine tank from your local dealer. You would
pull the mineral tank out of your brine tank and discard your brine
tank. A separate brine tank would take up more room but would hold more
salt. Or maybe you can find a brine tank inside of which you can put
your mineral tank, as in your current setup.

Your local man will probably try to sell you a whole new unit. If you
read up and know how a softener works and politely resist buying a new
one, probably you can fix it yourself or have somebody fix it for a
minimum labor charge.

How likely is it that this unit can be repaired economically? Thank
you in advance for all replies.

I'm guessing you can fix it for under $100.

A lot of softeners are rebranded units whose main components are built
by Autotrol, GE Osmonics, Fleck, and others. Start here to identify
your components:

You can also find some softener stuff on ebay.

I am not exactly an expert, but I was able to fix and overhaul my
34-year-old Autotrol.

Let us know what happens.
