How to Water Softener Maintenance
Your water softener protects your entire plumbing system, water heater, and appliances from the damaging effects of hard water scale. This maintenance task involves checking and refilling salt levels, breaking up any salt bridges (hard crusts that form over empty space), checking for salt mush at the bottom of the tank, and verifying the system is regenerating properly. A well-maintained water softener extends the life of your water heater, protects fixtures from scale buildup, and keeps soap lathering properly.
Cost to Skip This Task
Risk $500 – $5,000 in repairs
Why It Matters
Hard water causes scale buildup in pipes, water heaters, and appliances, reducing their lifespan by 30-50%. A functioning water softener protects your entire plumbing system. Check salt levels every 1-2 months. Keep salt at least one-third full. If water suddenly feels hard (soap doesn't lather), check for salt bridges before assuming a malfunction. Clean the brine tank annually.
Safety First
- Salt bags are heavy (40-50 lbs) - lift with your legs
- Do not mix different types of softener salt

Step-by-Step Instructions
Before You Start
Locate your water softener (usually in the basement, garage, or utility room). Check what type of salt it uses (pellets, crystals, or block).
- 1
Check the salt level in the brine tank - it should be at least 1/3 full
- 2
Look for salt bridges (a hard crust over empty space) by pushing a broom handle into the salt
If you feel a hard layer with empty space below, break it up carefully
- 3
Add salt if the level is low - fill to about 2/3 full
- 4
Check the brine tank for mushy salt buildup at the bottom (salt mush)
- 5
Verify the regeneration timer/schedule is set correctly
- 6
How to Verify Success
Salt level is adequate. No salt bridges. Water feels soft (soap lathers easily). No leaks around the unit.
When to Call a Professional
- Water is still hard after regeneration (service call $75-150, resin replacement $200-400)
- Unit is leaking (seal repair $100-200)
- Error codes on the control panel (diagnostic and repair $100-300)
- Brine tank has excessive salt mush that needs cleaning (professional cleaning $100-200)
