How often to service
Refill the salt tank every 1-2 months. Check the brine tank for clumping and clean it annually. Book a professional service visit once a year to clean the resin and test the system.
Is it worth it?
If your water is hard (7+ grains per gallon), the softener protects water heaters, faucets and appliances from scale. Scale buildup shortens appliance life and raises energy bills. Maintenance is cheap insurance.
