Softener emits a foul or rotten-egg odor from the brine tank or during regeneration

Safety first: Wear gloves and eye protection when handling bleach or cleaners.

• Clean brine tank: Empty the brine tank of salt and sludge. Wash the interior with a mild bleach solution (1/4 cup bleach per gallon of water), rinse thoroughly, and refill with fresh salt.
• Sanitize system: Follow Lindsay’s sanitization procedure, typically involving adding a small amount of bleach to the brine well and running a regeneration.
• Increase regen frequency: Program more frequent regenerations to prevent stagnant brine.
• Address source water: If odors persist, test for sulfur bacteria and consider pre-treatment.
