Cleaning The Salt Storage Tank

Because all salts contain some insoluble matter, (purified salt contains less than rock salt) your salt storage container will require occasional cleaning to keep your conditioner at peak operating efficiency.

Tools Needed:

  • Scoop
  • Clean bucket-size container
  • Philips head or straight screwdriver (depending on your unit)
  • Garden hose
  • Household scrub brush or sponge


  • Remove the salt storage tank cover and the cap from the brine valve chamber.*
  • Remove brine line nut (if necessary) and lift the brine valve out of the brine valve chamber and set aside in an upright position.
  • If you’d like to save any clean, dry salt remaining in the tank, remove it and place it in a clean container.
  • Using the scoop, dig out and discard as much remaining salt, water and debris as possible.
  • Remove the brine valve chamber by removing the screws on the side of the salt tank.
  • Remove the salt plate at the bottom of the brine tank.
  • Lay the salt tank on its side and direct a brisk stream of water from your garden hose to its inside to rinse out all residue.
  • Using a household scrub brush and a mild soapy solution, clean the salt plate. This will complete the tank cleaning.
  • Stand salt tank upright. Replace the salt plate. Place brine valve chamber in position and affix with screws.
  • Insert the brine valve into the chamber, replace replace brine line and nut (if necessary) and replace valve chamber cap.*
  • Fill the storage tank with 4 to 6 inches of water.
  • Fill the tank with salt about halfway – overfilling salt can lead to salt bridge.
  • Replace the salt storage tank cover.

 *Note-not all models have a brine valve chamber cap
