Salt pellets are used in salt-based water softeners to create a brine that cleans and recharges the resin beads inside the unit. This process helps reduce hardness minerals like calcium and magnesium. Softer water can help minimize scale buildup on fixtures, improve soap lather, and support consistent performance from plumbing and water-using appliances.

• Place pellets in the brine tank as directed by your softener’s manual.
• Maintain a steady salt level to help the system regenerate as needed.
• Check your manual for compatible types (pellets, crystals, or potassium-based) since recommendations can vary by model.

It depends on your water hardness, household size, and how often your softener regenerates. Usage can vary widely.

• Many 2–4 person homes with moderately hard water may use a bag in about 1–2 months.
• Very hard water or heavy use could shorten that to a few weeks.
• Small households or lighter hardness can stretch a bag longer.

To use salt efficiently (results can vary):

• Check the brine tank monthly and refill before it’s empty.
• Fix leaky faucets or running toilets that increase water consumption.
• If available, a demand-initiated (metered) setting can reduce unnecessary regenerations.
• Follow your unit’s recommended hardness setting and regeneration schedule.

You can shop water softener salt pellets on Walmart’s site and in many local stores.

• Online: Set your ZIP code to see what’s in stock, then choose delivery or store pickup where available.
• In store: Check availability in the app or on the product page before heading out.
• Options you’ll typically find: Single 25–50 lb bags, multi-packs, pellets or crystals, and specialty formulas like iron-fighting or potassium-based.

Tip: Review bag weight and plan for safe lifting or use a cart. Product pages include weight, type, and usage details to help you choose.

Both forms can work in salt-based softeners, but they behave a bit differently.

• Pellets: Compressed and uniform, they tend to dissolve evenly and can be less prone to bridging in humid conditions. They’re a solid choice for many brine tanks and higher-usage households.
• Crystals: Typically solar-evaporated flakes. They can work well in some systems but may be more susceptible to clumping or mushing in damp environments.

Consider your manufacturer’s guidance, local humidity, and water needs. If iron staining is a concern, look for pellets formulated to help with iron. Potassium-based pellets are also available as a sodium alternative. Always check your softener manual for compatible types.

Moisture is the main culprit behind clumping. A few simple habits can help keep pellets flowing freely.

• Keep bags sealed and store in a cool, dry spot off the floor (on a shelf or pallet).
• If transferring to a bin, use a container with a tight lid and label it clearly.
• Avoid damp basements or areas with condensation; rotate older bags to the front.

For the brine tank (follow your manual):

• Don’t overfill; keeping salt around one-third to two-thirds full can help limit bridging.
• If a crust forms, gently break it with a non-metal stick.
• Use only water-softening salt; de-icing products aren’t intended for softeners.
