Water Softener Maintenance: The Complete Schedule
How to maintain a water softener for maximum lifespan and performance.
Monthly tasks
Check salt level in the brine tank (keep it at least 1/3 full). Break up any salt bridges (a hard crust that forms above the water level, preventing proper brine making). Use the right salt: evaporated pellets are cleanest, rock salt is cheapest but leaves residue.
Quarterly tasks
Clean the brine tank if you see sediment buildup. Check that regeneration cycles are running on schedule (you should hear the system running in the middle of the night). Verify water feels soft by checking for soap lathering.
Annual tasks
Sanitize the resin bed with softener cleaner (e.g., Iron Out or Res Care). Inspect the control valve for leaks. Check bypass valve operation. Test water hardness before and after the softener to verify performance. Resin replacement: every 10-15 years ($100-200 for resin). Control valve: can last 15-25 years with proper care.
