Why is the right salt so important?
Water softening salt is used to regenerate the resins in your water softener.
The process removes lime from the water.
If you use the wrong salt, you risk:
- ❌ poor regeneration
- ❌ sludge formation in the salt pan
- ❌ blockage of the valve
- ❌ higher maintenance costs
- ❌ shorter lifespan of your device
✅ The right salt = hassle-free soft water.
