Steps to repair brine leaks:

  • 1. Inspect brine tank: Look for visible cracks or splits in the Aquasana brine tank body, especially near the bottom and fittings.
  • 2. Check brine line fittings: Tighten compression or push-fit connections at both the brine tank and control head. Replace any cracked ferrules or fittings.
  • 3. Inspect float assembly: Remove the brine well cover and lift out the float assembly. Check O-rings and seals; replace if worn.
  • 4. Avoid overfilling: Maintain salt below the top of the brine well and do not overfill with water.
  • 5. Replace tank if needed: If the brine tank is cracked, replace the Aquasana brine tank assembly.
