How often do I need to add salt to my water softener?
Your quick guide to keeping soft water flowing in Houston.
The short answer? It depends on your water hardness, your household size, and your softener’s capacity—but most Houston homeowners need to add salt every 4–8 weeks.
Why Salt Matters
Salt in the brine tank is what allows your water softener to recharge its resin beads and keep removing hardness minerals. Without enough salt, your softener stops softening—fast.
Factors That Affect Refill Frequency
Water hardness level — Higher hardness = faster salt usage
Household water use — More people = more water softened = more salt used
System size & efficiency — Larger, more efficient systems use salt less often
Pro Tip: The “Quarter Full Rule”
Never let your brine tank drop below a quarter full. Check it at least once a month and top off as needed.
