the unit doing or not doing?

I'm not detecting any change from when it was new. Call me a skeptic,
but 13 years seems
like a long time for a beast like this to function with virtually zero
maintenance. My
question is - is the mere presence of the 'slimy' feeling enough to
assure me that the unit
is, indeed, working? Perhaps not at peak efficiency, but at least
working?

As long as you have the feeling, the softener is working and not
allowing more than 1 gpg hardness to get through. I've seen many Fleck
control valves last service free for up to 20 years. Some backwashed or
regenerated every other night.
