Fleck softener emits a foul or musty odor from the brine tank or softened water.

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

• Clean brine tank: Empty the brine tank of salt and water. Scrub the interior with a mild bleach solution, then rinse thoroughly.
• Sanitize system: Follow Fleck’s sanitization procedure, typically involving adding a small amount of bleach to the brine well and running a regeneration.
• Increase regeneration frequency: Adjust programming so the softener regenerates often enough to prevent stagnation.
• Consider pre-disinfection: If the raw water has bacterial issues, consult a water treatment professional about chlorination or UV treatment upstream.
