A correctly sized and properly setup softener for "average" water
conditions on a municipal water system should regenerate every 6 or 7
days for longest resin life.

If there's iron in the water then more frequent regenerations are
preferred and a resin cleaner should be routinely used.

You can't tell the size of the softener by the size of the brine
tank... you CAN tell the softener by the size of the resin tank. A
specific size resin tanks hold a specific volume of resin and that
resin volume is what dictates the hardness removal capacity (size) of
the softener.
Well that's not all of it. The volume of resin in cubic feet and the
salt dose lbs dictate the capacity.

And all softeners have an adjustable K of capacity because they all
have an adjustable salt dose.

The length of time a regeneration runs for is about 1.5 hrs on average
and some softeners have no ability to adjust that and most consumer
manuals do not have any instructions on how to do it if the control
valve allows it..Better quality valves like the Clack WS-1 do allow
it.
