The answer to 'water softener maintenance' is to perform regular maintenance on your water softener to ensure it continues to function properly. This typically includes checking the salt level, cleaning the brine tank, and regenerating the softener on a regular schedule.
First, check the salt level in the brine tank and add more salt if it's low. You'll want to keep the tank at least half full at all times. Next, use a garden hose to rinse out any debris or buildup in the brine tank. Finally, run a manual regeneration cycle to flush the system and replenish the resin beads that remove minerals from your water.
