No one (here) can tell you IF your regeneration schedule is right or
wrong based on the volume of salt it uses or the time between
Demand/metered control valves regenerate when needed and based on the
size of softener you have, the type of resin you have in it and the ion
exchange required (raw water quality), the number of gallons between
regenerations, ETC.. Your softener may be working just fine, or maybe
not set up correctly. Is the water soft?
The capacity of a softener is dictated by the volume and type of resin
AND THEN the salt dose in lbs per regeneration. Thereby every softener
in the world has an adjustable salt dose. If you have a high efficiency
salt dose setting, and decide to use potassium chloride instead of
sodium chloride, you must increase the salt dose. Potassium is not as
efficient and sodium because cation resins are not made in the
potassium form, they are all sodium form. Depending on the salt
efficiency setting, you have to increase the salt dose as much as 30%.
Here's a link to explain all the above and more about correctly sizing
a softener and setting one up.
