How often do I need to add salt to the brine tank?

🧂 now, what the salt actually does:

Salt in your softener’s brine tank doesn’t go directly into your water—it helps recharge the resin beads that remove hard minerals like calcium and magnesium. During regeneration, the salty brine flushes the resin clean so it can keep doing its job.

If you run out of salt? Your softener stops softening. And your water starts to feel dry, filmy, or harsh again.

📆 how often should you add salt?

For most Houston households, you should check the salt level once a month and refill it every 6–8 weeks, depending on:

• Your household size and water usage

• The hardness of your water (Houston’s is pretty high)

• The type of softener system you have

• Whether your system regenerates based on a timer or demand

As a general rule, keep the salt level at least half full and never let it drop below ¼ tank. Letting it run too low can cause bridging, clogs, or system strain.

🛑 warning signs you’re low on salt

• Water feels hard again (soap doesn’t lather, stiff laundry, residue on glassware)

• Softener regenerates more frequently or not at all

• Visible salt is caked or clumped (a sign of salt bridging)

• Salt level hasn’t moved in a long time—could mean the system isn’t pulling brine
