Water Softener Settings for Re Gen ??

We've had this Water Softener going on 12 yrs now.. We live in a Rural Setting (Septic / Well) Hardness & Iron Content are an on going Issue in the area.. We have someone that changes out the RO Filters as well when needed.. Problem... Just recently the Settings on the Water Softener were Adjusted for the Re Gen Cycle Time.. Previously it was 775 gallons / 14 Days , took approximately 5 weeks to go through a bag of Salt Pellets.. The new settings are 1350 gallons / 7 Days , now it's a minimum of 11 weeks before I see signs of water starting to poke through the Salt in the Unit.. Once we see water it's time to add Salt.. Unfortunately the Tech doesn't live close by.. Presently the Salt level does go down as well as the Resin level in the Automatic Applicator.. Trying to Understand what determines what the settings are set at ?? Added to all this, settings were adjusted same time as both Canadian Salt Suppliers went on Strike.. We were using Windsor Pellets and had to switch to Sifto Chrystals.. Don't know if changing from pellets to chrystals had any baring on this ?? Thoughts & Opinions Appreciated, Cheers Thanks

 

The regen cycle should be set according to your water hardness level and the amount of water used based on the size of your softener. There are calculators and formulas online for setting the regen. My softener I just enter my water hardness and it calculates how long to go between regen cycles. Of course all of this depends on knowing your water hardness. Just saying it's "hard" isn't good enough. You need the number.
